I talked to a recruiter at a college career fair, and they reached out for on-campus interviews the following week. The process was smooth, and they interviewed about 20 other people as well. My interviewer was kind, but I was too nervous and messed up horribly. They told me I wouldn't continue in the process because of my poor performance about a week after, so they didn't take too long to get back. Overall, a decent experience, if only I hadn't messed up badly in the interview.
