Technical Questions

Walk me through how you would perform reconnaissance on a target organization during the initial phases of a penetration test. What tools would you use, and how would you avoid detection?

Why they ask this:* They're assessing your understanding of passive and active information gathering techniques, tool proficiency (Shodan, theHarvester, Nmap), and your ability to balance thoroughness with operational security.

Explain the differences between SQL injection, blind SQL injection, and time-based SQL injection. How would you exploit each one, and what mitigation strategies would you recommend?

Why they ask this:* They're evaluating your depth of knowledge in web application vulnerabilities, understanding of attack mechanics, and ability to provide actionable remediation advice to clients.

Describe your experience with common exploitation frameworks like Metasploit or Cobalt Strike. Can you provide an example of a complex payload chain you've built and explain the post-exploitation steps you took?

Why they ask this:* They want to confirm hands-on experience with industry-standard tools, your ability to chain exploits together, and your understanding of post-compromise activities and lateral movement.

How do you approach testing an OAuth 2.0 or SAML 2.0 implementation? What are the common misconfigurations you've encountered, and how did you validate the vulnerabilities?

Behavioral Questions

Tell me about a time when you discovered a critical vulnerability during a penetration test that the client's development team disagreed was exploitable. How did you handle the disagreement, and what was the outcome?

Describe a situation where you had to learn a new technology or vulnerability quickly to complete a penetration test. What was your approach, and how did you validate your understanding before presenting findings?

Can you share an example of when you had to compromise on scope or depth during a penetration test due to time or resource constraints? How did you communicate this to stakeholders, and what did you deliver?
