AMD Senior Architect interview questions

It took 45 days to get to a second round, which is an in-person interview in the AMD campus. I thought process was very slow. But no response after the final round. I would like to hear atleast some feedback after this round. I was a 3 hour interview process slotted 30 minutes with each manager. I got only 20% relevant questions to the technology or what I have applied for. However, I am not interested if they call with some feedback. Looks like they are more stable in hardware side, but not in software development. I don't want to get laid off, after one month or so...
