I applied through a recruiter. I interviewed at Meta (San Francisco, CA) in Sept 2017
Interview
First call is to get to know you as a person, see if your resume is accurate, judge your interest in the company. My recruiter was AWESOME (Facebook prioritizes this).
The second interview is where the knowledge is tested. I did well up until the last question and I floundered pretty hard. More details in the second question below.

Question 1
Open ended: what do you know about Memory Management in Objective C?
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.
