Meta Software Engineer for Android interview questions

First Round: call with HR to discuss background and interest in fb. Then several multiple choice questions on Android. If you answer enough questions correctly you move onto the next round. Second Round: Technical Phone Interview. An engineer from Android Team will call and ask coding questions. Coderpad is used. Compile is disabled. In retrospect, I was not prepared enough for the interview. The questions are not really that hard. I personally totally stumbled on binary tree traversal question, due to lack of preparation. Be sure to review all known algorithm questions in mid-difficulty level before the interview.
