Facebook Production Endineer

I’m really curious too. I haven’t heard much about the role online.

Tech stack and language is not important nor questioned, you’ll need solid understanding in CS fundamentals like OS/Networking. Also be prepared for system design questions which I think groking the system design interview is a good preparation material - the recruiter will send you a coupon code to study it if you’re invited to on-site interview

I agree that the language is not important for the interview. But for the job, PE mainly use python.
