The whole on-site interview was disorganized and chaotic. First, I was made to wait over 30 minutes in the freezing lobby in mid-November before the hiring manager showed up. From that point, every interview was delayed. Two out of six interviewers did not show up, and apparently, there was no prior communication about this. This forced the other interviewers to just sit around and make small talk with me for over an hour.

The interviewers who did show up confessed that my experience and education were very different from theirs and hardly asked anything technical. I was surprised, given that the hiring manager had obviously seen my resume before inviting me. There was really only one technical interview, which I thought I did quite well.

But after the interviews, there was no feedback for a month until I emailed HR. They replied back with a curt "Thanks, but we hired someone else."

Overall, a very negative experience, and one I didn't expect from a respected company like Intel.

A few basic questions on digital and wireless communications, estimation theory, random processes, etc.

Mostly questions based on work I had done before.
