What You’ll Be Asked
Security testing interviews assess your understanding of the OWASP Top 10, common vulnerability classes (SQLi, XSS, CSRF), and the tools used to detect them. You'll face questions about the difference between SAST and DAST, how to use OWASP ZAP or Burp Suite for basic penetration testing, and how to validate API authentication and authorization. Senior candidates are expected to discuss threat modeling, security test planning, and embedding security gates into CI/CD.
Topics Covered
Key areas interviewers evaluate when asking about security testing.
OWASP Top 10
Understanding the most critical web application security risks — injection, broken auth, sensitive data exposure, XXE, and more.
SQL Injection & XSS
How SQL injection and cross-site scripting attacks work, how to test for them, and how to validate that fixes are effective.
CSRF & Session Security
Cross-site request forgery, session hijacking, cookie security flags, and validating anti-CSRF token implementations.
API Security Testing
Testing authentication (OAuth, JWT), authorization (BOLA/IDOR), rate limiting, input validation, and API-specific OWASP risks.
SAST & DAST Tools
Static analysis (SonarQube, Snyk) vs dynamic analysis (OWASP ZAP, Burp Suite) — when to use each and interpreting results.
Security in CI/CD
Integrating security scans into pipelines, dependency vulnerability checks, container scanning, and shift-left security practices.
Sample Interview Questions
Questions based on real interview patterns. Practice answering these with AssertHired’s AI interviewer.
- 01
Walk me through the OWASP Top 10. Which vulnerabilities have you tested for, and how?
- 02
How would you test a login form for SQL injection? What payloads would you try?
- 03
Explain the difference between SAST and DAST. When would you use each in the development lifecycle?
- 04
A REST API returns a 200 OK when you access another user's data by changing the ID parameter. What vulnerability is this, and how would you test for it systematically?
- 05
How would you validate that an anti-CSRF token implementation is working correctly?
- 06
Describe how you would integrate OWASP ZAP into a CI/CD pipeline for automated security scanning.
- 07
What is the difference between authentication and authorization testing? Give examples of tests for each.

Frequently Asked Questions
Do QA engineers need to know security testing?
Increasingly, yes. While dedicated security teams handle deep penetration testing, QA engineers are expected to catch common vulnerabilities like XSS, SQL injection, and broken access controls during regular testing. This is especially true for SDET and senior QA roles.
What security testing tools should I learn for interviews?
Start with OWASP ZAP (free, widely used) and understand how SAST tools like SonarQube work. Familiarity with Burp Suite is a plus. More importantly, understand the vulnerability classes themselves rather than being dependent on any single tool.
How deep into security testing do QA interviews go?
Most QA interviews cover OWASP Top 10 awareness, basic SQL injection and XSS testing, API authentication testing, and security integration in CI/CD. Deep exploit development or cryptography questions are typically reserved for dedicated security engineer roles.
Can I practice security testing questions on AssertHired?
Yes. AssertHired's AI interviewer asks about OWASP vulnerabilities, security tooling, API security testing, and how to build security into your QA process. You receive scored feedback on your answers.
