I applied through an employee referral. The process took 1 week. I interviewed at Meta in July 2021
Interview
Had an initial phone screen for their research scientist position which is a 1 hour long screening. The interviewer jumped right into the interview and the first was a LC medium question which had to be solved within 20-25 mins since the second part was an applied stats questions on expectation and cdf, pdf derivations. The last part was supposed to be an applied ML question. For my part, took me quite a while for the stats question with lots of hints since my stats knowledge on pdf to cdf and expectation was a bit rusty. Overall seemed like a reasonable process if you prepare a little with the stats basics and practice some probability puzzles.
Interview questions [1]
Question 1
LC medium, applied stats on expectation of random variables
I applied online. The process took 2 months. I interviewed at Meta
Interview
7 Interviews, didn't receive an offer after the final round. Time-consuming process, which includes multiple rounds of technical interviews (design, coding, behavior, etc.) and a 1-hour research talk. The team leader was unpleasant to interact with.
recruiter call, technical interview, research interview, and job talk (presentation), hiring manager interview, everything was organized in the website so it was easy to navigate through the process, and recruiter was always responding super quickly
