They were unable to promptly meet my disability needs for a quiet working environment due to ADD, resulting in a major panic attack and my early departure.
They offered noise cancelling headphones but those never appeared weeks after being promised. They also offered to move my desk against a wall but it didn't happen either.
Additionally the job requirements that were presented to me were very far from what I was asked to do once I joined. There were a LOT of major added duties never described in the application/hiring process.
