Had to do a math/logic test which was pretty easy assuming that you have a firm grasp high school level math and are a logical thinker. There was some programming involved however they don't really seem to care about you getting the program to work exactly, just enough written to show that you know what you're doing.

I was originally contacted by a Recruiter by email and told that they were looking for math and physics majors, so I went to their website, looked at some of jobs, and went ahead and applied. About a week or two later I received an email from HR asking me to take an online personality test and to give some days and times that I would be available for a phone interview. And then a few days after the interview I received an email which stated that they would like to move forward with the recruitment process, the next step of which involves taking a skills assessment test.
