The interview was split into 3 stages:
An initial screening that has you take a behavioral test, and then another test that tests your cognitive reasoning and deduction skills.
My first round interview was quite nice. It was very technical and I had questions asked about my resume in the embedded world - FPGA, MCU, etc. I was also asked a few behavioral questions.
My last round interview was also a technical interview revolving around analog circuits and testing with some behavioral questions.
