Meta Research Scientist interview questions

Chat about research and topics related to my research, The discussion is very informal and spontaneous. Questions include both very detailed and very high-level questions. Usually it's a very detailed question, then extended to a high level question that tests the landscape view about the frontier research.

On-site, asked a bunch of sklearn, graph coding problems, and system design. Experience was moderate, but the guy asking the sklearn was making weird faces during the interview which was really bothering.
