I applied through a recruiter. The process took 4 weeks. I interviewed at Meta (Cupertino, CA) in Jan 2022
Interview
5 Round Interview Style. Mix of Coding, System Design, and Behavioral. There were a few general leetcode style questions asked on the coding section of the 5 round interview that were a mix between medium and hard.

Question 1
Given the root node of a binary search tree and two integers low and high, return the sum of values of all nodes with a value in the inclusive range [low, high].
The technical round hit me with a classic array manipulation problem: moving zeroes to the end without disrupting the order of non-zero elements. As I tackled it, I felt a wave of familiarity wash over me; I had just practiced a similar challenge on PracHub. The rest of the interview followed a straightforward path, with some easy behavioral questions sprinkled in. Overall, it felt very easy, but I wasn’t quite the right fit for what they needed, so I didn’t receive an offer.
