The interviewers were very polite and professional. Interviewers were very technical people. I interviewed with four people. Out of four, two of them asked me technical questions. The questions were wide-range: RC type circuits(Bode and step response), Hogge Phase detectors, TIA(trans impedance amplifiers). They wanted to check the fundamentals. Not all questions came from the resume. As I mentioned, some of them came from general engineering topics. The culture was friendly. I recommend that the interviewee studies his resume and then go over the passive networks, Bode plots, step response.
