For one job, I took an "programming aptitude" test along with 20 other people. For my current job, I was given an 3-page exercise that asked questions to test my familiarity with both EDI and Perl - "what does this code output?", "spot the error in this 204". The aptitude test was timed, the pop quiz was not (well, not explicitly - if I had taken more than 20 minutes I suspect I would not be working here). I consider myself fortunate that I have never encountered any "If you were an animal ..." type questions in interviews.
I don't think this really tells you much about the working environment. Everybody is looking for the magic formula. This will help them establish you have the technical chops for the job. If I were trying to fill a lead role, I think I'd be more concerned about your leadership experience.
