Hiring Managers: What is the pettiest thing you draw a line in the sand over when selecting candidates to hire/interview?

For me, if you put "Attention to Detail" as a skillset and you have spelling/formatting/grammatical errors in your application, you are an automatic no from me.

I've probably missed out on some good people, but I'm willing to bet I've missed out on more bullshitters and I'm fine with that.
