1 OA round, then called for an interview in which we need to solve 5 levels of LeetCode-style coding problems, need to pass at least 3/5 levels to pass this round,
I applied through an employee referral. I interviewed at OpenAI (San Francisco, CA) in May 2026
Interview
2 ML coding (60 min each)
2 General Coding (60 min each)
1 Hiring manager INTERVIEW(30 min)
I didn't get to onsite stage
But if i get there, it would be presentation + hm interview
2 ml coding rounds, 2 general coding rounds
ml codings: one pytorch round, one numpy round
general coding: 60-75min, doesn't require optimal solution, need to do it quickly to pass test cases
Interview questions [1]
Question 1
- given set of human labeler, labeling tasks, and model, give balanced assignment schedule for each (human, task), (human, model), (model, task) pairs
