I can't believe I did this...I still can't believe it. I submitted a cover letter for a job application....that had a TYPO in it!!!!!!! OMG! A flipping TYPO! It was one of those where I had read it about 15 times and one that spell check would not find. "Thank you for the opportunity to apply to the a So-and-So firm."
It asks specifically for good writing and presentation skills! OH CRAP!
