This is a tiny, minor, inconsequential thing, but I’m telling you anyway because I’m neurotic about small things:
If you are currently employed, the dates on your resume for your current job should end with “present.” For instance:
Chocolate Teapot Maker, 2009 – present
Chocolate Teapot Maker, 2009 – 2013
If you do the latter, many of us will wonder if you’re still employed there or whether you left. And if it happens to be, say, December 2012, and your most recent job says “2009 – 2012,” we’ll wonder if you’re still there or whether you left 10 months ago. And then we’ll spend time asking you, when you could have been clear about it from the beginning.
Minor, very minor, but worth doing right.
