I had a 1:1 interview for a first round, and talked to hardware engineers about interest in power electronics and control systems and the interview went well and I was informed 3 weeks after that I made it to final rounds in Seattle. It took about 3 months for them to set up the final rounds and mentioned that they told more people than they should have about final rounds, nevertheless I was selected. I arrived at Seattle thinking I will continue my interview process for the same position in electronics hardware engineering, but I was surprised to see that my 5 interviews were all about mechanical engineering, structural mechanics, and product design which was not made clear to me before starting. Needless to say I was unprepared for that kind of interview and didn't do as well as I hoped.
