Let me just start by saying this, if you are reading this and are not an attractive white 20 something, the odds are already stacked against you (though there did seem to be the one token black guy, and a few white washed Asians). The interview process was pretty straight forward. One phone interview, online homework module, and then several in person interviews. I made it to the second before being told I had not been selected to move forward. If I recall correctly, there were 3.
Phone screen -> Online Assessments -> Interview with team leaders, partially in group, before they pulled you aside individually-> Interview with Sales Manager -> Interview with both aforementioned parties and their president.
The questions didn't seem to hard or stressful on a mechanical level, but I really think what they're looking for is cultural fit. Again, if you're an extroverted white kid aged 23-28, you should fit in.
Additionally, I kept in touch with 3 people in the initial interview, one of whom ended up getting an offer. He mentioned there was no Drug Test, just something to know :)
