What Interviewers Evaluate

Frequently Asked Questions

Which certifications are most valued?

AWS Security Specialty, CISSP, and CKS (Certified Kubernetes Security) are the most requested. CompTIA Security+ is a common baseline. Multiple certifications across cloud and security domains strengthen your profile.

Is this different from a security engineer?

Infrastructure security engineers focus specifically on the platform layer—cloud, network, OS, and container security—rather than application security. The role is more DevOps-adjacent than traditional security.

How hands-on are the interviews?

Expect scenario-based questions about threat modeling, architecture review exercises, and potentially live configuration or script review. Some companies include capture-the-flag style challenges.

How important is programming?

Python and Bash scripting are expected for automation. Terraform and CloudFormation for security-as-code are essential. You should be able to write security policies, detection rules, and compliance checks as code.
