It’s a document sent to tons of people. Revised by tons of hiring managers. Can’t you spend 5 minute looking at a dictionary? If you cant be bothered to spend 5 minutes researching this for an important document, what makes me think that you will spend 5 minutes trying to be good at your job. Lack of care on your resume is lack of care on lots of other things.
There was even one time they forgot to give me the resume... that was probably the funniest interview ever. They got the job too.
Bullshit. There are many things person may care about and many things they may not. If this position is unrelated to professional writing, it's just irrelevant. Are you questioning their abstract ability to "care" and trying to translate spelling care to job care? Bad news, it doesn't translate (aside from the fact that ideal perfectionists can't get shit done ever; your best candidate still figures out the ideal form of his resume and is too anxious to click "publish").
