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.

For me, the behavioral interview was the toughest one, not the coding nor the system design. The questions were heavily focused on how you handle negative experiences, such as dealing with a big setback, criticism, or negative feedback. It was unusual because I didn't have that many negative experiences in my previous job. They didn't ask anything from the sample 26 questions that the recruiter sent.
