It was a two- step process:
First they bring you in for a group interview. Once you enter, they take a picture of you, and give you a badge to wear. You then are called in to meet with a manager, who sits you in a green room and asks, "what do you think of the company?" and records your 30 second response. Upon doing so, you're taken to a room and you watch a few of the training managers present the company and explain the different job titles. After that, you meet with a hiring manager again, who asks you a few questions, looks over your resume, and tells you to expect to hear an answer soon. I didn't expect the interview to take 3+ hours, but it did. Some people walked out because they weren't expecting it to last so long.
The second part of the interview is a "Test-drive" where they have you do a bunch of activities including a typing test and a general IQ test. This is a full-day, so expect to be there for at least 8 hours. This day was pretty fun, as they have you dress up, take pictures, and role-play in a "FBI vs Criminals" theme.
After that, they call you into a room and let you know whether you'll be a good fit for the company, or not.
