Meta Research Scientist interview questions

Two phone coding interviews, 5 onsite interviews: 3 coding, one ML interview, one "fit" interview where they ask the next question before you finish answering the last question. It was an exhausting experience, and there was little to no focus on my background and past projects. Their feedback is always that they are looking for "signal" and they use that as an excuse to do additional coding interviews sometimes.

First, I applied online. A recruiter called me to do a phone screening. Then the recruiter passed my name to the team. They scheduled a video interview. I did the video interview with a current member of the team.
