What Interviewers Actually Value
Based on hiring manager feedback:
Ranked by Impact:
- Demonstrated experience - Projects, bug bounties, incident handling
- Relevant certifications - Validates baseline knowledge
- Technical depth - Deep expertise in 1-2 areas
- Communication skills - Can explain security to non-technical stakeholders
- Cultural fit - Collaborative, continuous learner
Reality Check: Certifications open doors, but experience closes deals. A candidate with a vulnerability disclosure on a major product often outweighs one with multiple certifications.
