Meta Software Engineer interview questions

I had interviewed for a number of positions (full time and intern) before, and was never successful until this, my final chance. Luckily, things went in my favor and I was offered a full-time position. My recruiter was quick and very responsive over email. I already had an offer with another company at the time, and thus, my recruiter was able to expedite me through the already quick interview process. I had one coding challenge to be turned in whenever it was completed, a non-technical interview over the phone, and two on-site interviews. My first on-site interview was an interview with my recruiter plus a technical interview. My second on-site was a series of four technical interviews. All in all, I was very pleased with the sincerity and speed my recruiter put in and of course, being given an offer made was the cherry on top :).
