I was working 100 hour weeks and not given any time for documentation or knowledge transfer. The code was certainly self-reading but it was a very complex system, especially security wise as it was a bank. Their other developers were juniors and couldn't understand it so they threw it out and started from scratch. I quit with no notice because I was burnt out and promised a vacation when the product launched. They renegged after denying me a raise multiple times. So I left.
