Meta Software Developer interview questions

I originally applied online and spoke with one recruiter. She did not feel I was a good fit for the team she was recruiting for but referred me to another recruiter at Facebook. I spoke with the second recruiter on the phone and she set a technical interview on-site in Menlo Park. The guy who interviewed me was very nice and while I didn't do a great job on the question, they liked me enough to schedule a full day of interviews. After some preparation, I came onsite for a full-day of technical interviews with a lunch break in the middle. The pace was very fast but I knew it would be like that so I was prepared. The questions were difficult especially in the limited amount of time. Everyone was very nice. There was a design round where I was asked to design an iPhone app that was unrelated to social networking.

Two days after internal referral, recruiter contacted me and set-up a phone interview. The coding problems are standard and not difficult. Two weeks later, I went to their head quarter for the onsite interview. There are 4 rounds of technical interviews, involving coding and database design. Wait almost 4 weeks before the recruiter got back to me and offered me a position.
