Panel of about 9 people of whom thought to be a group of engineers. Turns out it was 7 interns who did not hold the position I was interviewing for, one full time Web Developer, and then the actual colleague I would be working with day to day. I was soft-balled easy questions that got convinced the panel that I didn't need to take a technicals skills test. Talked to my direct report who was very agreeable at the time...
Then onto the personality test...
Now, I have no issues passing these kinds of tests, they are easy and generally even the math and english portions are easy enough after being out of school for 10 years, but... I almost bailed on the whole interview process because of how long, monotonous, and ridiculous this specific personality test was. Like others have said your fate lies in the hands of this personality test which is old and antiquated, just like the company, so it makes sense.
In the end it turns out I was a good fit skills-wise for the company, culturally that is not the case.
