OpenAI Software Engineer Swe II interview questions

Very standard interview process, one architecture, one coding, and onsite after. Interviewers are nice. System Design went into a lot of details, so it was kinda hard, and I didn't do super well

Worst interview I ever had, my interviewer didn't show up for the coding interview and I wasted 30 minutes of my time waiting for them. Then had my system design interview which I thought I did pretty well in, ended up getting rejected and having my coding interview for tomorrow cancelled.
