Is this rejection rude? Should I apply to another position in the same University? I applied for an adjunct position and never heard back from the school. I emailed them to learn about the status of my application and this is the response I received: Your resume is competitive but doesn't meet our needs. Am I overreacting for thinking that this is a rude rejection letter (well, one sentence!)? There is another position open, but I am hesitant to apply. What would you do if you were me? 
p.s.1 Sorry, I know this is a petty question, but I have become very picky since I want to work in a healthy environment.
p.s.2 I am pretty confident I am not underqualified for the position.
This seems to me like a normal rejection letter.  They normally don't really contain any information except "you didn't get the job".  Some letters do go on for longer about "we had so many great candidates and we wish we could hire them all, blah blah blah" but I wouldn't really say that makes them more polite.

In particular, I certainly would not draw any conclusions about the "healthiness" of the environment from this letter.  It might be a good department or a bad one, but this letter doesn't help you to determine which; you'll need to investigate that in other ways.  See:
