Gads another one that posts to every usenet group with the word Oracle in its name. What does this inquiry have to do with 3 of the 4?

I'm in agreement with Hans. Keep pushing your resume out until you find a job where they are more interested in quality of performance than rules.

Also be advised that a job interview is a two way street. I never, make that NEVER EVER, take on a project without inquiring as to whether essential tools will be given to me or whether I will need to fight for them. The last time, during an interview, someone said to me that such tools would not be available I terminated the interview got up and walked out the door. The look on their faces was priceless. I understand that the person that got the project ... also got the tools.
