I applied through a recruiter. The process took 3 weeks. I interviewed at Meta in Dec 2020
Interview
There is an initial call with an HR representative, followed by one phone-screen with an engineer. You are supposed to solve two 15-20 minute programming puzzles (though in my phone screen i was only asked to solve one somehow).
If you pass the phone screen - it is followed then by 3 additional programming interviews, each of which is of the same format (two 15-20 minute puzzles) and a behavioral interview.
Interview questions [1]
Question 1
Describe an implement an algorithm for finding a local minimum value in an array of numbers (a local minimum is a value where both neighbouring values are equal or larger).
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.
