Eight Graduate Cyber Security Analyst interview questions, and what the interviewer is thinking

1. How has your degree prepared you for a graduate cyber security analyst role, and why did you choose to apply to a graduate scheme?

Why they ask: To see how well you connect your studies to the role and what draws you to a structured programme.

2. How would you use Wireshark to investigate a packet capture from a machine that might be infected?

Why they ask: To check practical network analysis skills beyond theory.

3. If you saw many failed logins followed by a successful one in a SIEM, how would you write a query to find that pattern, and what would it indicate?

Why they ask: To test your ability to turn a threat idea into a basic search, a key analyst skill.

4. Which Windows event IDs are useful in security investigations, and what would you look for in them?

Why they ask: To check you know the practical log evidence analysts rely on.

5. How could you use Python to help with security tasks, and can you describe something you've written?

Why they ask: To test coding ability in a practical, security-oriented context.

6. What is the difference between brute force, password spraying and credential stuffing attacks, and how can they be detected?

Why they ask: To check you understand common authentication attacks and their distinct signatures.

7. You're triaging alerts and see a user logging in successfully from a country they've never worked in, right after multiple failed attempts. What would you do?

Why they ask: To test your triage process and ability to escalate appropriately as a new analyst.

8. Tell me about a university or personal project involving security that you're proud of, and what you personally contributed.

Why they ask: To check depth of practical experience and your ability to describe your own role.

A sample answer to question 1

How has your degree prepared you for a graduate cyber security analyst role, and why did you choose to apply to a graduate scheme?

My degree gave me a solid grounding in networking, operating systems and programming, and my final-year modules on network security and digital forensics were the ones I enjoyed most. In forensics, I analysed disk images with Autopsy and learned about evidence handling, which taught me patience and attention to detail. My dissertation involved detecting anomalous traffic with a simple machine learning model, so I'm comfortable working with data and writing Python. Outside the course, I've done TryHackMe's SOC Level 1 path and taken part in a university capture-the-flag team. I'm drawn to a graduate scheme because I want structured development: rotating through different teams, working with mentors, and gaining recognised certifications while handling real alerts and incidents. A theoretical understanding is only the start, and I want to see how security decisions are made in an organisation with real constraints. I'm also keen to find which area suits me best, whether detection, incident response or threat intelligence, before specialising.

Common mistake to avoid: Reciting the degree syllabus; no examples of practical work
