Interview
After the initial recruiter call, I moved on to a 45-minute virtual interview. The session was a mix of LeetCode-style algorithmic problems, along with some probability and statistics questions. The coding portion wasn't too difficult—I'd say it was around the Medium level.

Reach out directly without oa, give some basic probability and stats question, also ask about something on the resume. the interviewer is pretty nice, and answered all questions, still got rejected lol
Two phone screens, one was a Leetcode Easy coding problem along with general ML questions. Second asked some probability statistics questions. Last one was about my research and a general feeler about my knowledge of economics and current events.
