Not much of a process. Was sent a link to complete an application and aptitude test that they estimated to take over 2 hours. I cannot stress how unrelated the test was to the position I applied for but it was just off putting for me. I will not devote that much time to an APPLICATION. I do not care how they see this, but they should know this process is likely why they have a high turn over. Starting your potential employees off with a bad taste in their mouth about your processes.

Take an aptitude test then go through an interview process if you pass. I could see the test being difficult for a lot of people, I was lucky because I just got done with teaching half a semester of high school algebra and that's what basically half the test. I would definitely spend a couple of hours on Kahn Academy and freshen up on algebra if you're really interested.
