Very unlike what I expected. I was told there would be 45 minutes for a personal interview and 45 minutes for a math exam. I prepared very hard only to show up with six other people interviewing at the same time as me, and I only got asked three questions, standing up, simultaneously with other candidates. The rest was just the math test. Expected to be there 1 1/2 hours and was only there for 45 minutes. The math test was a bit too difficult for me, too.
