Common Questions During a Cybersecurity Job Interview

by | Jun 3, 2024

A cybersecurity job interview is similar to a certification test. You have to study, practice, and recall various problems with the lessons learned from them. Like any other job interview, having the necessary technical skills is only half the process. You must impress the interviewer, demonstrate your expertise, and show how you can add value to the organization. This is also a time to practice your soft skills. When you meet a recruiter or hiring manager for a cybersecurity job interview, you will face two types of questions:

  • Personal questions to understand your background/goals.
  • Technical questions to assess your cybersecurity knowledge/experience.

To help you prepare for your cybersecurity job interview, we’re sharing a list of the most common questions asked by recruiters and a guide to crafting your answers. Add a personal touch by sharing some of your past experiences, even if they stem from a lab in a cybersecurity program.


Personal Questions in a Cybersecurity Job Interview

Before discussing the technical aspect, craft an elevator pitch that describes who you are. Summarize your schooling, background, achievements, skills, and motivations. Prepare answers for questions such as:

  • Why are you looking for a job change?
  • What are your greatest accomplishments as a cybersecurity professional?
  • What assets do you bring to the team?
  • What are your weaknesses?
  • What was a great challenge at work, and how did you overcome it?

Use these questions to explain your motivations for seeking a new position. For instance, do you want more responsibilities or a better salary? Highlight the assets you will bring to the team, your skills (both soft and technical), and your impact on previous roles. Don’t forget to explain why you want to work for that organization. To make a real impact, mention the tech blogs you follow, the sites you use to stay updated on industry news, and your thoughts on recent cybersecurity incidents.


Technical Questions in a Cybersecurity Job Interview

Once the interviewer understands your profile, you will move on to technical questions. This is your moment to shine! Demonstrate your ability to apply technical knowledge in real-life scenarios. Mention different security situations and how you would mitigate the damages.


Examples of Theoretical Questions

  • What is Cryptography? Cryptography refers to techniques for securing information and communication from third parties or adversaries.
  • Explain the main differences between asymmetric and symmetric encryption. Symmetric encryption uses the same key to encrypt and decrypt, while asymmetric encryption uses different keys.
  • What is the difference between IDS and IPS? IDS (Intrusion Detection System) only detects intrusions, while IPS (Intrusion Prevention System) detects and prevents intrusions.
  • Explain the difference between Penetration Testing and Vulnerability Assessment. Vulnerability assessments are automated scans identifying weaknesses, while Penetration Tests are rigorous manual processes designed to identify and exploit vulnerabilities.
  • What are the differences between HTTPS, SSL, and TLS? HTTPS is the secured version of HTTP. SSL (Secure Sockets Layer) is the predecessor of TLS (Transport Layer Security).
  • What is Port Scanning? Port Scanning identifies open ports and services on a host. Hackers use it to find exploitable information, while system administrators use it to verify security policies.
  • Explain traceroute. A traceroute lists all points a packet passes through and helps identify where a connection stops or breaks.
  • Explain phishing and how to prevent it. Phishing is a cybercrime where targets are tricked into providing sensitive information. Prevention includes regular security awareness training and simulated phishing attacks.
  • What is a firewall? A firewall monitors network traffic and blocks data packets based on security rules.
  • What is a botnet? A botnet is a network of infected computers controlled by an attacker, used for DDoS attacks, data theft, and spamming.
  • Explain brute force attacks and how to prevent them. A brute force attack gains access by trying all possible credential combinations. Prevention includes using strong passwords, limiting login attempts, and using CAPTCHAs.
  • Explain the TCP Three-Way Handshake. A three-step process in which a client and server establish a connection to transfer data.
  • Mention some common cyber-attacks. Use this opportunity to discuss recent attacks, such as the SolarWinds hack or the attempt to poison a Florida town’s water supply.
  • Explain the differences between a worm and a virus. Viruses require human interaction to spread, while worms act independently.

Scenario-Based Questions

When answering scenario-based questions, mention real-life experiences, outcomes, and lessons learned. Here is a short guide for crafting your responses:

  • What steps would you take to prevent outdated software from being exploited? Automate software updates as soon as new versions are released.
  • What do you look for when identifying a compromised system? Signs include slow network activity, unusual traffic, unexplained data changes, and unsuccessful login attempts.
  • How do you secure a server? Use secure connections (HTTPS, FTPs, SSH), complex passwords, multi-factor authentication, VPNs, firewalls, and regular updates.
  • How would you reset a password-protected BIOS configuration? Locate and toggle the BIOS clear or password jumper, or use generic passwords if available.
  • How do you protect your data? Encrypt data, back it up, use anti-malware systems, automate software backups, and secure wireless connections.
