Meta Software Developer interview questions

Got a call from a recruiter at Facebook. Very helpful and they motivate you to try and get through the process easily. They give you books, links, courses, etc which could be helpful for appearing in the interview. He told me about the interview process in details. The initial screening started from the same round and I was asked a few basic questions about Android. Assuming you need to clear x/ 8-9 questions that were being asked. Then the round was with a developer from facebook which was for around 45-60 mins. The only problem that I faced in the process was that I didn't get any feedback so that I can atleast prepare and appear again for the interview. While I was atleast expecting a feedback for the same.

1. HR interview - HR calls you and ask you questions about you and tell you about the process 2. Phone screen - On a specific time you connect to a remote code panel, and code for around 35 min 3. 4 interviews on-site - you have 3-4 Tech interviews and one Software Design (as a graduate you don't have this part)
