Meta Sr. Software Engineer interview questions

Meta has some of the best recruiters out there. They are professional, informative, friendly, and quick in their responses. The process takes about a month from tech screening to on-site to getting an offer. The questions are designed "not" to be straightforward, so you have to revise and update your approach accordingly. Practicing on Leetcode helps tremendously.

Started off with a touch base call with the recruiter. He was quote helpful and shared resources for interview preparation. You also get a chance to talk with a developer to understand more about the expectation of the interview. This was followed by a 45 minute coding interview. I got one easy and one hard LeetCode. The interviewer is a developer so some hints were provided but I would not rely too much on it. Next was the main interview with 45 minutes each. This entails 2 separate coding interviews, 1 product design and 1 behavioral. That is far as I got.
