Meta Software Developer interview questions

I was contacted by a recruiter through LinkedIn. We scheduled a phone interview. The phone interviewer asked me about my background and then a coding question. He let me know that I did well at the end of interview. The next day, I got a call from recruiter and told me that they would like me to come onsite. I was also forwarded to another recruiter. Both the recruiters had been helpful along the way. I had two coding rounds, two design rounds and one behavioral round onsite. I may have made couple of mistakes in behavioral round, and some mistakes in other rounds. I was not very confident of getting through, but thought there could be a slim chance. I did not hear back from the recruiter for seven days, so I followed up. The recruiter mentioned she will get back to me as soon as she has an update. Three days later, I received a reject email. Overall, I liked the interview process and everyone was great. I would have appreciated a call, just as a courtesy. The lack of courtesy seemed to me that the recruiter did not seem as much enthusiastic after on-site compared to before the on-site interview. It is understandable though, but she was thoroughly professional whenever I worked with her. One more thing, if Facebook has so high a rejection rate, it is better to have phone screen + a video call screen, before bringing people in. It will save them some money, and save time from my side.

phone interview with recruiter, then phone interview with one programming question the process was quick and fair. they were super nice the whole time and didn't stall with the final answer
