This is the one area most people at OO heavily respect: the training department.
They do their job and do it well. Classes run approximately every two weeks. I haven't heard of any sort of delay in training unless it was due to a training failure. Even then, the delay is minimal (1 week tops) I'm told.
Most folks I know at 9E finished training 1-2 months after a new hire at OO was already out on-line.
