I applied through a recruiter. I interviewed at OpenAI (San Francisco, CA) in Apr 2025
Interview
HR round - 30min talk about resume, why openai and why this role?
One day later got the phone interview invitation
2 60min sessions back to back: 1 coding, 1 system design
Interview questions [1]
Question 1
Common / well known system design question; for coding, not leetcode style, but more like implementing a feature step by step.
