Got a tour of their office in the Compuware building a while back while interviewing for a position at Quicken. Pretty cool place, but probably a brutally chaotic environment to actually program or get shit done.
I was given a few days to complete a take-home challenge, and went above-and-beyond to include persistence and real-time functionality. Weeks would go by, and when I would inquire about the status of my application, I would be told nobody got a chance to look at my code/application. I don't blame the recruiters, but it does seem like your suspicion about the place being "brutally chaotic" is spot-on. My colleague left after a few short months to work as a freelancer.
Not to mention you are in the same building with other properties like Quicken and Bedrock.
Fun for a visitor, obnoxious for an employee.
