There was no interview at all. You basically have to know someone working there to get in. Once you're called in, you simply go for a test with something like 10-15 questions, all showing pictures of money and asking you to count how much was there. Pass the test and you're hired, assuming you pass the background check. The people giving the test don't speak to you so much as one word, besides introducing themselves and handing out the tests.

Personal, asked about previous work, customer service views. Asked about interests outside of work. Everything depends on the hiring manager's mood.
