Very professional yet, they made you feel at ease. In the first interview you are given a timed test. If all goes well, you are then emailed a "behavioral" test to determine if you're personality will suit the company. They get back to you right away whether you will get the position or not.

I applied online and received a call from a recruiter for a phone interview. After the phone interview, I was scheduled for a face to face interview. During the face to face interview, you are to complete a math and comprehension test that is timed. It wasn't too hard. If you pass, they will then send you an e-mail to complete personality assessments. If you are a good fit for the position, they will ask you to come in for a second interview where you are interviewed by two or possibly three hiring managers from the department. It's a lengthy process, but they truly seek the best employees to work for the company.
