I applied through a recruiter. I interviewed at Meta in Jul 2020
Interview
There are two 45 mins sections for coding interviews. Another simple coding problem in the behavioral interview round. If you prepare 200 Leetcode problems under the Facebook tag, you should be able to crush the coding problems. For system design and ML design, I think I did average on ML design and bad on system design. That's probably why I got rejection.
The overall interview process is good. The only thing I'm not happy with is the ML design part, there is no question asked on the ML fundamentals at all.
Got connected through a friend who currently works at Meta, which fast-tracked me into the interview process. The first round was a coding challenge where I tackled a task involving user-item interaction logs. The subsequent rounds included a deeper discussion on designing an ML system for video recommendations. Lucky for me, I had spent hours on prachub.com prepping, which helped me nail the coding question on similarity computations. Ultimately, I received an offer but decided to pursue a different opportunity. Overall, it was a solid experience.
Interview questions [2]
Question 1
Design an ML system to rank and recommend short-form videos (Reels) in a user's feed, including how you'd choose features, handle cold-start, and pick an evaluation metric.
Applied online. Received a recruiter screen within two weeks covering background and role fit. Followed by a technical phone screen with coding (LeetCode medium-hard, arrays/graphs). Then a virtual onsite with 4 rounds: 2 coding, 1 ML system design (recommendation/ranking system), and 1 behavioral. Interviewers were professional and gave time to ask questions. Results communicated within a week post-onsite.
First stage was a screen round with behavioral and 2 leetcodes, one medium one hard, 15-17 min each. If selected, loop is 4-6 interviews. 2 desgin, 2 coding, 1 behavioral.

Question 1
idiotic questions that can't be answered in depth in 35 minutes design, like "your solution isn't going to work, how will you handle it?" yea no sht this is a baseline bro, wait 15 seconds and ill talk about the optimal one.
