Q: Should I include a job on my resume that I had for only 12 weeks?

A: Yes. 
And I'd love to leave it at that. But I know that I need to elaborate because as you all read this, I can hear many of you saying “Really? Twelve weeks doesn't really count as long enough to include on a resume.” Oh, but it does.

This is an honesty issue. Regardless of how bad it might look or how irrelevant it might seem, you've got to tell the truth about your professional background on your resume. Every morsel of it. I do understand why you wouldn't want to include this position as part of your official background. It's a short stint, a blink of an eye, a flash, a blip…an instant. And think about all the questions it will raise. It could be a terrible bruise on an otherwise pristine resume. Why should such a small period of time cause such a potential fuss? Nobody will care anyway, right?
