Meta Research Scientist interview questions

I have had 2 virtual screening rounds, I am scheduled for a virtual onsite full loop in 2 weeks. Screening rounds had 2 leet code problems each. 2 easy, 2 medium problems.

First you have a conversation with the recruiter. They will give you all the details to prepare for the next rounds. Then you'll have a technical screening with live coding and some stats/econ questions as part of a small case study, and last is the on-site with 6 interviews (coding, case-study, behavioral)
