I created a candidate profile on intel.com/jobs in October 2010. I was not actively looking for work, so I wasn't bothered when they did not contact me.

Then, in December, I received an email notifying me that I had been matched to a job and to apply if I was interested. I did apply.

The next day, I got an email notifying me that I had been selected for a phone interview and a link to schedule it. I did schedule the interview.

Staffing called me at the scheduled time, and the interview lasted about 15 minutes. It was mostly verifying what was on my resume and questions about my background. There were a few technical questions, but nothing too hard.

I was contacted the day after the phone interview and asked to schedule an in-person interview. I did schedule it.

The interview started at 1 PM and took all afternoon. There were two panels of three engineers each, and a one-on-one with the group lead. There were lots of technical, behavioral, and safety questions.

The atmosphere was friendly and professional, but it lasted way too long. I did not expect it to last that long and did not get lunch in before going to the interview.

What is a mass flow meter?
