Meta Research Scientist I interview questions

Phone interview with the HR about background and expectations on the job. Called in for on-site interview. 1 hour talk on my research topic and 5 back to back interview, lunch with a few team members. Overall experience was positive, some interviewers were more arrogant than others (a Facebook AI guy who dialed in, he was unprepared and asked me questions about my talk which didn't make much sense (probably didn't listen to my talk). One interviewer was a core developer (20 something young folk) asked me a coding question trying to make the question harder than it was. Changed the question in the mid-way which made it harder to finish. Behavioral questions followed a simple coding question (which later i found out that the question was wrongly stated).

Recruiter emailed me for a phone screening. After a week, an onsite was scheduled. Went in to meet with the hiring manager who went over the position and the company. He asked me to talk about myself first and then asked a more technical question. He then let me ask a few questions. It went a little bit over half an hour.
