Meta Software Engineer interview questions

I had the option of an onsite interview or phone interview for the first round. I chose onsite. They first showed the office, which was pretty cool of course, and then I was led to a room with an interviewer. The interviewer had a very different background, and we had a brief chat and it was clear to me that despite being intimately aware with what facebook was doing for the role I was interviewing for, that topic was never touched. The interviewer did not care for my background or the role I was interviewing for. I was asked one question - I gave it my best shot. I could definitely have done better, but it was certainly annoying to be judged based on how I solved that one question, instead of a more subjective conversation based on my background.

It started out pleasant with a phone screen conversation with the recruiter but then went downhill from there. They were very late for the technical phone interview, but I brushed it off as an anomaly. Then came the onsite. First interviewer was nice and intelligent but seemed to be expecting me to provide a very specific solution that he had obviously rehearsed very well. Though what I provided was close, it looks like he wrote me off because I didn't get that exact solution. The next interviewer was a very jaded engineer who clearly didn't want to be there. Unresponsive to questions. It was very awkward and put me off in a major way. The experience interview was the only good interview in my opinion and I had a good exchange. The system design interviews were somewhat unforgiving. Tough luck if you haven't worked already at a company like, well, Facebook. After more than a week, the recruiter told me -- in recruiter speak of course -- that I was a terrible candidate and should think before applying again. Perhaps it's the process that needs work.
