Anthropic Data Scientist interview questions

Had great RPI. MPI was strange. HM was not very friendly, seemed smug and disengaged, and kept saying "well I think I have everything I need". I then waited 3 (!) weeks before I got an update and only because I probed and sent a follow-up myself. The recruiter told me in the rejection message that they couldn't share any feedback for me which is really frustrating.
