Applied on my own, was told they were not interested. Was referred by an employee a day later and then a couple days after I got the email saying they were not going to pursue the interview process I got a call wanting me to come in for an interview. Took several exams prior to interview, then took some more when I arrived for the interview. The interview itself was easy, was told I'd hear back in 10-15 days if a manager was interested in a second interview with me. I heard back that she day to take additional tests. Then I heard back about 3 weeks later for a second interview. I'm still currently in the process.
