Applied for a senior position and quickly had a 30m call with a recruiter. Lots of skill overlap so the next steps were to go to hiring manager review. Received an automatic rejection the next day. Recruiters, don't schedule calls unless the hiring manager has already +1'd the person. If you have to, never ever send an automatic rejection after meeting with the person. It makes you look like you don't know what you're doing (which from what I've heard about the company internally, it tracks)
2 rounds phone screen(1 coding + 1 system design) and 4 rounds onsite interviews(1 coding + 1 design + 1 deep dive + 1 behavior).
general good experience but need fast coding
The technical round kicked off with a question about finding the length of the longest substring without repeating characters. I felt prepared, and as we discussed my approach and time complexity, I could sense I was on the right track. Later, there was a behavioral round where I described my experiences and team dynamics. The wild moment came when I realized I had literally seen this exact problem on prachub.com during my prep a week earlier. Afterward, I received an offer, which I happily accepted. Overall, a rewarding experience.

Envié una solicitud electrónica. El proceso duró 3 semanas. Acudí a una entrevista en OpenAI (San Francisco, CA) en abr 2026
Entrevista
First round with HR: HR was a little impatient, probably very busy.
1 coding round, multi-part coding problem under 1 hour with tests passing. Plan your time wisely. Don't spend time on stuff like pseudo coding in earlier parts. Interviewer wasn't very engaged.
1 system design round. Interview was smart and nice.
Reject on the following day.
