Had 2 interviews, the first one being a virtual call with 4 people in it. The supposedly last interview was a f2f, which is not too different from the first that i think a virtual one would suffice imo. Was asked a range of questions from android/ios architecture, decoding a source code with not much context given, intercommunication between chips. All in all, felt that the interviewer was looking for a very specific answer and the questions were very broad and domain specific
