Made it to the second interview and did well until they wanted me to solve math problems quickly while they stared at me waiting for the answer. I was so flustered I got it wrong and I'm pretty sure that's why I didn't get the job. But maybe that's why they do that. To see how well you work under pressure. I wasn't prepared for that at all.

Phone interview and then a couple weeks later I received a call to come to the campus and meet the team I'd be working with. Also have to take an IQ test before hand.
