Applying for a new job shouldn't be this stressful & them being so unprepared is absurd considering the company.
It definitely speaks volumes about the environment that you will be subjected to for 8+ hours a day & its fair that you choose not to put up with it.
I have also experienced having to quit shortly after starting a new job, I soon realized that my efforts were not going to be matched or acknowledged in a place where there was little to no organization & the supervisor could treat you as he pleased, if he even allowed you to speak to him that is since he was always so "busy". :s
