Meta Software Developer interview questions

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.
