I got an on campus interview from a campus networking event despite the fact that I am not a hardware person. The interviewer was really nice and it lasted for about 30 mins.

I was initially contacted by HR about the role which I applied online for HID team. HR was prompt in scheduling an half hour interview with the hiring manager and explained the hiring procedure. I was contacted by the hiring manager and there's no response after number of attempts to follow up about the interview results from both HR and hiring manager. During the day of interview, HR contacted me with a short notice that hiring manager would not be available to interview but another Senior Firmware QA engineer would interview for the role as it's likely to report directly to the same engineer going further. Overall felt a waste of time and ultimately not hearing back from them.
