First they reach out to you and you get a coding screen, then they schedule a phone screen (coding) after you pass, you get to do a full on-site loop. It includes take-home assignment and multiple rounds which will start in the morning and end in the evening.
Interview questions [1]
Question 1
DP (hard), study systems and building consumer applications
Recruiter screen then moved to a same day coding + architecture rounds. The people were friendly, but I found the questions difficult and hard to complete in the allotted time. The bar is very high these days, and short of perfection and strong internal referrals, the odds of success are low.
I applied through an employee referral. I interviewed at OpenAI (San Francisco, CA)
