Brief phone interview (20 minutes), if all goes well then you visit for an IQ test, personality tests, and a writing test. I was not selected for a follow-up in-person interview.
Had I looked at Glassdoor I probably would have been more prepared for the aptitude tests. I was taken a little off guard and fell into a groove of noticing patterns a bit late in the exam. But beyond entry-level jobs (where inexperience is high), I don't think such tests really have a place in the interview process, so I didn't expect it. They appear to rely HEAVILY on the tests also.
There was also a writing portion, which was pretty fair and straightforward.
A deep criticism for the company is that they look way too hard for "natural talent" based on these exams, when the most valuable people learn to adapt to their own personal weaknesses, not just rely on strengths. The personality tests are especially bogus in my opinion. There is no way for these tests to properly analyze people for workplace performance who actually have experience.
As an example, questions of the Kolbe index ask what you are most and least likely to do, some of them about building things and working with your hands. I am definitely least likely to do physical labor, not because I don't enjoy it or am not capable, but simply because as a writer I usually am not putting together desks. I imagine this test said I am very unlikely to actually do legwork, which is pretty inaccurate.
On the flipside, it shows that they at least are taking steps to try and build a bright team, so I imagine that doesn't stop after the interview process. It looked like a very positive work environment. I would recommend applying, with the understanding that the hiring process is pseudo-scientific.
