Cybersecurity Interview Questions — Entry-Level Guide 2026

What Are Cybersecurity Interview Questions and Why Do They Matter?

Cybersecurity interview questions for entry-level roles primarily test foundational knowledge of networking, the CIA triad, common security tools, and incident response — topics aligned with the CompTIA Security+ SY0-701 exam objectives and the NICE Cybersecurity Workforce Framework published by NIST.

Cybersecurity interview questions test whether you can think clearly about security — not whether you have years of experience. That is good news for career changers.

If you are switching from a non-IT background, the interview is where you prove that your study, lab work, and certifications translate into real understanding. Hiring managers know you do not have five years of SOC experience. What they want to see is that you understand the fundamentals, can explain them clearly, and can connect security concepts to practical decisions.

This page covers 20 common cybersecurity interview questions for entry-level and SOC analyst roles. For each question, I explain what the interviewer is really testing and provide an answer framework you can adapt to your own experience.

I used to dread the idea of technical interviews. Coming from real estate and aged care, I felt like I had nothing relevant to say. But the more I studied, the more I realised that understanding why a firewall matters is more valuable in an interview than memorising port numbers. Interviewers want to see how you think, not how much you have memorised. That shift in perspective made interview preparation feel manageable instead of terrifying.

Quick Answer

What are cybersecurity interview questions? Entry-level cybersecurity interviews test foundational knowledge of networking, security concepts, common tools, and scenario-based incident response — aligned with the CompTIA Security+ SY0-701 exam domains. Why it matters for beginners: According to CyberSeek, there are over 500,000 unfilled cybersecurity positions in the US alone, and strong interview performance is what separates hired candidates from equally certified applicants. Key framework: The NICE Cybersecurity Workforce Framework (NIST SP 800-181) — defines the knowledge, skills, and abilities employers look for across all cybersecurity roles.

What Does an Entry-Level Cybersecurity Interview Look Like?

According to the NICE Cybersecurity Workforce Framework, entry-level security roles focus on foundational knowledge areas — networking, operating systems, and security concepts — rather than advanced exploit development or reverse engineering.

Before diving into specific questions, it helps to understand what entry-level interviews actually look like.

Before diving into specific questions, it helps to understand what entry-level interviews actually look like.

What you might expect	What actually happens
Deep technical questions about advanced exploits	Foundational questions about networking, security concepts, and basic tools
Trick questions designed to catch you out	Scenario-based questions that test your reasoning process
Only technical questions	A mix of technical, behavioural, and scenario questions
Needing to know everything	Needing to demonstrate solid fundamentals and a willingness to learn
Your non-IT background is a weakness	Transferable skills (communication, problem-solving, stakeholder management) are valued

Most entry-level security roles — SOC Analyst, Junior Security Analyst, IT Security Associate — test the same core areas: networking fundamentals, security concepts, common tools, incident response basics, and how you handle unfamiliar situations.

How Should You Structure Your Interview Answers?

The STAR method (Situation, Task, Action, Result) is widely recommended by hiring managers and career coaches for structured interview responses — adapted here with a Technical detail component specifically for cybersecurity roles.

Before you memorise answers, learn a framework for structuring them. This works for almost any technical interview question.

The STAR-T framework for security interviews:

• Situation — Set the context (what is the scenario or concept?)
• Technical detail — Show you understand how it works
• Action — What would you do about it?
• Result — What outcome does this produce?
• Tie-back — Connect it to the role you are interviewing for

You do not need to use this framework rigidly for every question, but having a structure prevents rambling and ensures you cover what the interviewer is looking for.

Key Definition

STAR-T framework is a structured interview response method that organises answers into five components: Situation (context), Technical detail (how it works), Action (what you would do), Result (expected outcome), and Tie-back (relevance to the role). Adapted from the standard STAR method used across industries, with a technical component added for cybersecurity interviews.

What Networking Questions Should You Expect?

Networking fundamentals are tested in virtually every entry-level cybersecurity interview because they underpin all security monitoring, analysis, and incident response — as reflected in CompTIA Security+ SY0-701 Domain 1 and the CompTIA Network+ N10-009 exam objectives.

These test whether you understand how systems communicate — a non-negotiable skill for any security role.

Question 1: Explain the TCP three-way handshake

What the interviewer is testing: Whether you understand how reliable connections are established, which is foundational for understanding network attacks.

Strong answer framework:

The TCP three-way handshake establishes a reliable connection between two systems. The client sends a SYN (synchronise) packet to the server. The server responds with a SYN-ACK (synchronise-acknowledge). The client replies with an ACK (acknowledge), and the connection is established.

This matters for security because attackers can abuse this process. A SYN flood attack sends thousands of SYN packets without completing the handshake, exhausting the server’s resources. Understanding the handshake helps you recognise this in logs and packet captures.

Tip: If you have used Wireshark in your home lab, mention that you have seen the three-way handshake in packet captures. Practical experience stands out.

Question 2: What is the difference between TCP and UDP?

What the interviewer is testing: Whether you understand transport layer protocols and can explain trade-offs.

Strong answer framework:

TCP is connection-oriented — it establishes a connection, guarantees delivery, and delivers packets in order. UDP is connectionless — it sends packets without establishing a connection, does not guarantee delivery, and is faster because it has less overhead.

Security relevance: TCP is used for web browsing, email, and file transfer where reliability matters. UDP is used for DNS, video streaming, and VoIP where speed matters more than perfect delivery. Attackers can exploit both — TCP SYN floods target connection handling, while UDP floods target bandwidth. DNS amplification attacks abuse UDP’s connectionless nature.

Question 3: What is DNS and why is it a security concern?

What the interviewer is testing: Whether you understand a critical internet service and its attack surface.

Strong answer framework:

DNS (Domain Name System) translates human-readable domain names like example.com into IP addresses that computers use to communicate. It is often called “the phone book of the internet.”

DNS is a security concern because it is trusted by default and often unencrypted. Attacks include DNS spoofing (returning fake IP addresses to redirect users), DNS tunnelling (hiding malicious traffic inside DNS queries), DNS cache poisoning, and using DNS for command-and-control communication. Monitoring DNS queries is one of the most valuable things a SOC analyst can do because almost all network activity involves DNS.

Question 4: What common ports should a security analyst know?

What the interviewer is testing: Practical knowledge that you will use daily in log analysis and alert triage.

Port	Service	Why it matters for security
22	SSH	Remote access — brute force target
25	SMTP	Email — phishing delivery, spam relay
53	DNS	Name resolution — DNS tunnelling, spoofing
80	HTTP	Unencrypted web traffic
443	HTTPS	Encrypted web traffic — still used by malware for C2
3389	RDP	Remote Desktop — high-value brute force target
445	SMB	File sharing — ransomware lateral movement (WannaCry)

Tip: You do not need to memorise hundreds of ports. Focus on these high-value ports and be honest about using references for less common ones. Say “I know the critical ports from my study and lab work, and I use reference material for uncommon ports” — that is how professionals work.

What Security Concepts Questions Are Most Common?

Core security principles — including the CIA triad, defence in depth, and least privilege — form the foundation of every cybersecurity role and are among the most predictable interview topics, as documented in NIST SP 800-12 (An Introduction to Information Security).

These test your understanding of fundamental principles covered in Security Concepts.

Question 5: What is the CIA triad?

What the interviewer is testing: Whether you understand the foundational model of information security.

Strong answer framework:

The CIA triad stands for Confidentiality, Integrity, and Availability. Confidentiality means data is only accessible to authorised people. Integrity means data is accurate and has not been tampered with. Availability means systems and data are accessible when needed.

A real example: in a hospital, confidentiality means only the treating doctor sees patient records. Integrity means the medication dosage has not been changed incorrectly. Availability means the records are accessible during an emergency. Ransomware attacks primarily target availability by encrypting data.

Why career changers can excel here: If you worked in healthcare, finance, education, or government, you already understand why data needs to be private, accurate, and available. Use examples from your previous career.

Question 6: What is the difference between a vulnerability, a threat, and a risk?

What the interviewer is testing: Whether you can use security terminology precisely.

Strong answer framework:

A vulnerability is a weakness in a system — an unpatched server, a misconfigured firewall, or a weak password policy. A threat is something that could exploit that vulnerability — a ransomware group, a phishing campaign, or a disgruntled insider. A risk is the probability that a threat will exploit a vulnerability and the impact if it does.

Risk = Threat x Vulnerability x Impact. Security teams prioritise based on risk, not just vulnerability count. A critical vulnerability on an internet-facing server with sensitive data is a much higher risk than the same vulnerability on an isolated test system.

Question 7: What is the difference between IDS and IPS?

What the interviewer is testing: Whether you understand detection versus prevention controls.

Strong answer framework:

An Intrusion Detection System (IDS) monitors network traffic and alerts on suspicious activity but does not block it. An Intrusion Prevention System (IPS) sits inline and can actively block malicious traffic in real time.

The trade-off: an IDS has zero impact on legitimate traffic but requires someone to respond to alerts. An IPS can stop attacks automatically but risks blocking legitimate traffic if a rule is too aggressive (a false positive). Many organisations start with IDS to understand their traffic patterns before moving to IPS.

Question 8: Explain defense in depth

What the interviewer is testing: Whether you understand layered security and why single controls are insufficient.

Strong answer framework:

Defense in depth means using multiple layers of security controls so that if one layer fails, others still protect the asset. Instead of relying entirely on a firewall, you combine firewalls with endpoint protection, patching, multi-factor authentication, network segmentation, logging, and tested backups.

The analogy I use: it is like a medieval castle. There is a moat, then outer walls, then inner walls, then the keep. An attacker has to get past every layer. Even if they breach the outer wall, the inner defences still slow them down and give defenders time to respond.

What Tool and Technical Questions Should You Prepare For?

Entry-level interviewers expect familiarity with Wireshark, Nmap, and SIEM platforms — the core tools used daily in SOC analyst roles, as identified by the SANS SOC Analyst Skills Assessment and CyberSeek career pathway data.

These test whether you have hands-on familiarity with common security tools.

Question 9: What is Wireshark and when would you use it?

What the interviewer is testing: Familiarity with the most common network analysis tool.

Strong answer framework:

Wireshark is a network protocol analyser that captures and inspects network traffic in real time. A SOC analyst would use it to investigate suspicious network activity, analyse malware communication patterns, verify whether data was exfiltrated, or troubleshoot network issues.

For example, if an alert fires for unusual traffic to an external IP, you might use Wireshark to capture packets and see what data is being sent, what protocol is being used, and whether it matches known malicious patterns.

Tip: If you have used Wireshark in your home lab, describe a specific exercise — even a simple one like capturing a DNS query or HTTP request. See the Wireshark guide for practice exercises.

Question 10: What is Nmap and what would you use it for?

What the interviewer is testing: Whether you understand network scanning and its security applications.

Strong answer framework:

Nmap is a network scanning tool that discovers hosts, open ports, running services, and operating system information on a network. Security teams use it for vulnerability assessments, network inventory, and verifying that only expected services are running.

A basic example: nmap -sV 192.168.1.0/24 scans a local network and identifies what services are running on each host. If you discover an unexpected open port or an unpatched service, that is a finding worth investigating.

Legal note: Only use scanning tools against systems you own or have explicit written permission to test. Unauthorised scanning is illegal under the Computer Fraud and Abuse Act (US), the Computer Misuse Act (UK), and the Criminal Code Act 1995 (Australia).

Question 11: What is a SIEM and how does a SOC analyst use it?

What the interviewer is testing: Whether you understand the primary tool of a SOC analyst.

Strong answer framework:

A SIEM (Security Information and Event Management) collects logs from across the organisation — firewalls, endpoints, servers, cloud services, applications — normalises them into a common format, correlates events, and generates alerts based on detection rules.

As a SOC analyst, you would use a SIEM to monitor for security alerts, investigate suspicious activity by searching across log sources, identify patterns that indicate an attack, and document your findings. Common SIEMs include Splunk, Microsoft Sentinel, IBM QRadar, and Elastic Security.

What Scenario-Based Questions Should You Expect?

Scenario-based interview questions evaluate your incident triage process and logical reasoning — skills that the NIST SP 800-61 (Computer Security Incident Handling Guide) defines as essential for all security analysts, regardless of experience level.

These test your ability to think through real situations — and they are where career changers can really shine.

Question 12: You receive an alert that a user’s account is making login attempts from two different countries within 10 minutes. What do you do?

What the interviewer is testing: Your incident triage process and logical thinking.

Strong answer framework:

This is an impossible travel alert — a user cannot physically be in two countries 10 minutes apart. My steps would be:

1. Verify the alert — Check if it is a known false positive (VPN usage, cloud services with distributed IP ranges)
2. Check the user’s normal behaviour — Is this user known to travel or use VPN? What is their typical login pattern?
3. Look for additional indicators — Failed login attempts, password changes, unusual file access, new MFA device enrollment
4. Contain if suspicious — If the activity looks malicious, disable the account or force a password reset and MFA re-enrollment
5. Document and escalate — Log your findings and follow the incident response playbook

Question 13: A user reports they clicked a link in a suspicious email. What steps do you take?

What the interviewer is testing: Your incident response fundamentals and ability to stay calm.

Strong answer framework:

1. Gather initial information — Ask what the email looked like, what the link was, whether they entered any credentials, and what device they were using
2. Isolate if needed — If malware delivery is suspected, disconnect the device from the network (but do not power it off — that destroys volatile evidence)
3. Check for credential compromise — If they entered a password, force an immediate password reset and check for unauthorised access
4. Analyse the email — Check headers, sender domain, link destination, and whether other users received the same email
5. Scan the endpoint — Run endpoint detection tools to check for malware
6. Block the indicators — Add the malicious URL and sender domain to block lists
7. Document everything — Create an incident ticket with timeline and findings

This is directly related to the incident response process.

Question 14: Your organisation discovers that an employee has been accessing files they should not have permission to view. How do you investigate?

What the interviewer is testing: Whether you understand access control principles and insider threat investigation.

Strong answer framework:

1. Review access logs — Determine what files were accessed, when, and how often
2. Check authorisation — Verify whether the permissions were correctly configured or if there was a misconfiguration
3. Determine intent — Was this accidental (user stumbled onto accessible files) or deliberate (user actively sought out restricted data)?
4. Preserve evidence — Ensure logs are preserved and document the timeline
5. Escalate appropriately — Involve management, HR, and legal as needed, depending on severity and organisational policy
6. Remediate access — Fix the permissions issue and review similar access across the organisation
7. Review controls — This incident likely means the organisation needs better implementation of least privilege

What Behavioural Questions Do Cybersecurity Interviewers Ask?

According to LinkedIn’s Workforce Report and CyberSeek employer data, communication, adaptability, and continuous learning rank among the top five skills hiring managers seek in cybersecurity candidates — making behavioural questions a critical component of every interview.

These test soft skills that are critical in security roles — communication, learning ability, and teamwork.

Question 15: Tell me about a time you had to learn something completely new quickly

What the interviewer is testing: Your learning ability, which is the most important trait for a career changer.

Strong answer framework for career changers:

This is your strength. Use a real example from your career change journey. Describe what you needed to learn, how you approached it (courses, labs, self-study, certifications), what challenges you faced, and what you achieved. Be specific about timelines and outcomes.

Example: “When I decided to transition into cybersecurity from [your previous field], I had no IT background. I created a structured learning plan starting with CompTIA A+, built a home lab to practice networking and security concepts, and passed Security+ within six months while working full-time. I documented my progress in a blog, which helped reinforce what I learned and demonstrated my commitment to potential employers.”

Question 16: How do you stay current with cybersecurity threats and trends?

What the interviewer is testing: Whether you are self-motivated and developing professional habits.

Strong answer framework:

Mention specific, credible sources:

• CISA advisories for active threats
• MITRE ATT&CK framework for attack techniques
• Krebs on Security or BleepingComputer for industry news
• SANS Internet Storm Center for daily summaries
• ACSC advisories for Australian-specific threats
• Security podcasts or YouTube channels

Then explain your routine: “I spend 15-20 minutes each morning scanning CISA advisories and BleepingComputer headlines. When something is relevant to what I am studying, I dig deeper and try to understand the technical details.”

Question 17: Why are you transitioning into cybersecurity?

What the interviewer is testing: Motivation and commitment.

Strong answer framework:

Be genuine. Connect your motivation to something real — a specific incident that caught your attention, a realisation about the importance of security in your previous industry, or a desire for more intellectually challenging work. Then show what you have done about it — certifications, labs, self-study, community involvement.

Avoid generic answers like “I heard it pays well” or “there are lots of jobs.” Show that you understand what security work actually involves and that you are committed for the right reasons.

What Advanced Beginner Questions Should You Prepare For?

These questions test slightly deeper understanding — covering topics like cryptography, vulnerability prioritisation, and Zero Trust — that align with CompTIA Security+ SY0-701 exam objectives and are common for roles requiring Security+ or equivalent certification.

These questions test slightly deeper understanding and are common for roles that require Security+ or equivalent knowledge.

Question 18: What is the difference between symmetric and asymmetric encryption?

What the interviewer is testing: Cryptography fundamentals.

Strong answer framework:

Symmetric encryption uses one shared key for both encryption and decryption — it is fast and used for bulk data encryption (AES). Asymmetric encryption uses a key pair (public and private) — it is slower but solves the key distribution problem (RSA, ECC).

In practice, systems like TLS use both: asymmetric encryption to securely exchange a symmetric session key, then symmetric encryption for the actual data transfer. This gives you the security of asymmetric key exchange with the speed of symmetric encryption.

Question 19: A vulnerability scanner reports 500 findings. How do you prioritise remediation?

What the interviewer is testing: Whether you understand risk-based prioritisation.

Strong answer framework:

Not all vulnerabilities are equal. I would prioritise based on:

1. Severity — CVSS score and whether a known exploit exists in the wild
2. Exposure — Is the vulnerable system internet-facing or internal only?
3. Asset value — Does the system contain sensitive data or support critical business functions?
4. Exploitability — Is there a public exploit available, or is the vulnerability theoretical?
5. Compensating controls — Are there other controls that reduce the risk even if the vulnerability is not patched immediately?

A critical vulnerability with a public exploit on an internet-facing server with customer data gets immediate attention. A low-severity finding on an isolated test system goes to the bottom of the queue.

Question 20: Explain the concept of Zero Trust

What the interviewer is testing: Whether you understand modern security architecture.

Strong answer framework:

Zero Trust is a security model that eliminates implicit trust. Instead of assuming that users and devices inside the network are safe, Zero Trust requires continuous verification of identity, device health, and context before granting access.

The three principles are: verify explicitly, use least privilege access, and assume breach. In practice, this means strong authentication on every access request, granular access controls, micro-segmentation, and continuous monitoring — regardless of whether the user is inside or outside the corporate network.

What Are the Limitations of Interview Preparation?

Even with thorough preparation, interview outcomes depend on multiple variables — including the specific interviewer’s priorities, team culture, and market conditions — which is why the NICE Framework emphasises demonstrating adaptability and problem-solving over memorised answers.

Interview preparation has its own pitfalls.

Good approach	Common mistake
Understanding concepts and explaining in your own words	Memorising scripted answers that sound rehearsed
Saying “I do not know, but here is how I would find out”	Making up an answer and getting caught
Connecting answers to your lab experience or study	Giving purely theoretical answers with no practical context
Asking clarifying questions before answering	Jumping to an answer without understanding the question
Being honest about what you do not know yet	Overstating your experience or skills
Preparing questions about the team and role	Having no questions for the interviewer

The “I don’t know” strategy: It is better to say “I have not worked with that specific technology yet, but based on my understanding of [related concept], I would approach it by…” than to fake an answer. Interviewers respect honesty and problem-solving ability.

How Do Australian Cybersecurity Interviews Differ?

The ASD Essential Eight Maturity Model and the Australian Privacy Act 1988 create interview topics unique to Australian roles — with hiring managers expecting candidates to understand Essential Eight mitigation strategies, IRAP assessment requirements, and ACSC incident reporting obligations.

Australian cybersecurity interviews have some specific nuances worth preparing for.

Essential Eight knowledge: If you are interviewing for roles in Australian government or government-adjacent organisations, expect questions about the ASD Essential Eight mitigation strategies. Be prepared to explain each strategy and how you would assess or implement them.

IRAP and security clearances: Some Australian roles reference the Information Security Registered Assessors Program or require security clearances. If the job listing mentions IRAP or clearances, research the requirements before the interview.

Incident reporting: Australian organisations may ask about the obligation to report cyber incidents to the ACSC (Australian Cyber Security Centre) under the Security of Critical Infrastructure Act 2018. Understanding the regulatory landscape shows maturity.

Privacy Act awareness: With the increased penalties following the Optus and Medibank breaches, expect questions about the Australian Privacy Act 1988 and what “reasonable steps” to protect personal information means in practice.

Common Australian interview questions:

• “How would you implement MFA across a Microsoft 365 environment?” (Essential Eight)
• “Walk me through how you would restrict administrative privileges in a Windows domain” (Essential Eight)
• “A user reports a phishing email — what is your process?” (incident response)
• “How would you explain a security risk to a non-technical executive?” (communication skills)

Summary and Key Takeaways

Cybersecurity interviews test thinking and communication more than memorisation.

• Focus on understanding concepts well enough to explain them in your own words with practical examples.
• Use the STAR-T framework (Situation, Technical detail, Action, Result, Tie-back) to structure your answers.
• Career changers should lean into transferable skills — communication, problem-solving, learning ability, and industry knowledge from previous careers.
• “I do not know, but here is how I would find out” is always better than making something up.
• Lab experience and portfolio evidence (home lab, write-ups, blog posts) differentiate you from other entry-level candidates.
• For Australian roles, prepare for Essential Eight, Privacy Act, and ACSC-related questions.
• Start interview preparation early — it is a skill you develop over weeks, not days.

Individual results vary. Interview outcomes depend on preparation, the specific role, the hiring manager’s priorities, market conditions, and many factors outside your control. This guide provides frameworks, not guarantees.

Frequently Asked Questions

What questions are asked in a cybersecurity interview?

Entry-level cybersecurity interviews typically cover networking fundamentals (TCP handshake, common ports, DNS), security concepts (CIA triad, defense in depth, least privilege), tools (Wireshark, Nmap, SIEM), scenario-based incident response questions, and behavioural questions about learning ability and motivation. The mix depends on the specific role.

How do I prepare for a cybersecurity interview with no experience?

Build a home lab and document what you learn. Study core concepts through certifications like Security+. Practice explaining concepts out loud in your own words. Prepare specific examples of how your career change journey demonstrates learning ability, problem-solving, and commitment. Portfolio evidence like lab write-ups and blog posts differentiates you.

What should I do if I do not know the answer to an interview question?

Be honest and demonstrate your problem-solving approach. Say something like: I have not worked with that specific technology yet, but based on my understanding of the related concept, I would approach it by researching the official documentation, testing in a lab environment, and consulting with more experienced team members. Interviewers value honesty over fabricated answers.

How technical are entry-level cybersecurity interviews?

Entry-level interviews focus on fundamentals rather than advanced technical skills. You should understand networking basics, the CIA triad, common attack types, basic tool usage, and incident response concepts. Most questions test whether you can think through security problems logically rather than whether you can write exploit code.

Do I need certifications to get a cybersecurity interview?

Certifications like CompTIA Security+ help get your resume past initial screening, but they are not strictly required. Some employers value demonstrated skills through home lab work, CTF participation, or relevant projects. However, in competitive markets, Security+ significantly improves your chances of getting interviews.

What behavioural questions are common in cybersecurity interviews?

Common behavioural questions include: Tell me about a time you learned something new quickly. Describe a situation where you had to explain a technical concept to a non-technical person. How do you handle pressure or ambiguity? Why are you transitioning into cybersecurity? How do you stay current with security trends? Career changers should prepare specific examples.

How important is a home lab for interview preparation?

A home lab is extremely valuable for interviews because it provides concrete examples to reference in your answers. Instead of saying you understand Wireshark theoretically, you can describe a specific packet capture you performed. Interviewers consistently report that candidates with documented lab experience stand out from those with only certification knowledge.

What is the best way to practice for cybersecurity interviews?

Practice explaining concepts out loud, either to yourself or with a study partner. Record yourself answering questions and review the recordings. Join cybersecurity Discord communities or local meetups for mock interviews. Write up your understanding of key topics in a blog or notes — if you can write it clearly, you can explain it clearly.

Are Australian cybersecurity interviews different from US interviews?

The core technical content is the same, but Australian interviews may include questions about the ASD Essential Eight, the Australian Privacy Act, ACSC incident reporting obligations, and IRAP requirements for government roles. Australian organisations also tend to value practical experience with Microsoft 365 security and the Essential Eight maturity model.

How long should I prepare before applying for cybersecurity jobs?

Start applying once you have a solid understanding of networking and security fundamentals, at least one relevant certification like Security+, and some documented hands-on experience from a home lab or platforms like TryHackMe. For most career changers, this takes 6 to 12 months of consistent study. Do not wait until you feel completely ready — interview experience itself is valuable preparation.
