I got my resume accepted at a campus career fair. I received an email to schedule a phone interview within about a week.

The phone screen lasted 30 minutes. The interviewer did not initially state the position, but wanted to ask me questions first. After some in-depth questions about a project I listed on my resume, he informed me that it was a position related to that project and he thought I might have relevant experience (which I did not).

Very intense questions about experience listed on my resume.

I went into a lot of technical detail about how I designed a certain PCB, what frequencies it operated at, what problems I ran into, and how I fixed them.
