I received a call from a recruiter at Facebook. They were very helpful and motivated me to navigate the process smoothly. They provided resources such as books, links, and courses, which could be beneficial for interview preparation. The recruiter explained the interview process in detail.

The initial screening round involved basic Android questions. I assume it was necessary to answer at least 7 or 8 out of the 9 questions asked.

Following that, there was a 45-60 minute interview with a developer from Facebook.

The only issue I encountered during the process was the lack of feedback. I was expecting some feedback, at the very least, so I could prepare and reapply for the interview.

Focus on DS and try to write code for sample programs as much as possible.
