They use a set of canned questions and a panel grades you on your response. Like "tell me about a time when you made a mistake at your previous employer, what did you do to fix it?", or "tell me about a time when you disagreed with a coworker, what steps did you take to get them to leave you alone?". The BEST scores are generally for presenting your answer in a logical way. Presentation can weigh more than content. They are more impressed with your speaking skills than your actual answers.
The average worker is a 50+ white male, born within 20 miles of Canton Ohio, willing to work 50 hours a week forever (theres not much to do in Canton anyway).
This company has WAAAAY too many meetings. I probably averaged 24 hours of meetings per week, including some 8 hour staight ones. Upper management has nothing to do all day, so they schedule meetings to look like they are busy.
