I applied through an employee referral. I interviewed at Meta
Interview
I had my friend referred me to the intern position. It took about 3 weeks to hear from a recruiter. The process was pretty easy. After only one phone interview I was invited to go onsite. The phone interview takes 45 minutes. First talked about one of my previous projects. Then two technical problems.

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.
