Meta Software Developer interview questions

Emailed recruiter who's email I had from last year's internship interview. Probably due to large amount of applicants, they kept losing my information and taking a very long time to get back to me. Took around 3 weeks to schedule a first-round phone interview. After passing, I told them I had a deadline within a week - they were able to schedule an onsite that was 3 days later, and I received an offer 2 days after my onsite. Initial phone screen scheduling was frustrating, but they more than made up for it by getting back to me so quickly after the interview and working with my timeline.
