I applied online, they responded really fast and send me a personality/IQ test to complete. After you pass that, someone from HR will contact you via phone and arrange an in person interview and an in person test (to show them that it is actually you who did the test). Once you pass this interview as well, you will get an interview with your department manager - for me it was with two different managers. After you pass everything they will have you do a drug test before receiving the offer.

I had to apply online. Then I was to take a test that took about two hours. Then I was scheduled an interview, then take another test that takes an hour in front of thw same person who interviewed me then I got another interview. Then the last step was to get another interview but I had froze and did bad on my last interview.
