Arm interview questions

The level of interview was intermediate. I had total of 3 technical rounds, which was filled with questions related to my resume. The first round was filled with coding questions and some really interesting logical questions. later to that i was called for a second round , which included all possible questions from basic electronics to VLSI based questions . Majorly all concepts from elecronics were possibly asked to me. the next day I was asked to appear for another technical interview. I was very skeptical about this, as I wasnt expecting a third round. But this round aslo included technical questions. Pure technical. to be clear, all the interviews were virtual, taken on MS teams. All the 3 interviewers were very patient, to have listened to me for all 1 hour long interview. yes all interviews were 1 hour long. They told me were i could improve, and were very friendly and acceptable.
