Make sure to avoid these mistakes, so they don’t cost you a shot at the job.

1. Using a Cutesy Email Address for Correspondence

Example: cutiepie@domain.com

You Might Think: It’s a clever, memorable email address everyone will get a kick out of.

The Employer Will Probably Think: I can’t believe someone would actually list this email address on her resume, let alone use it to correspond with me. Will she do the same thing on the job if I hire her? Yikes!

2. Putting a Silly Message on Your Answering Machine

Example: A is for academics, B is for beer — and one of those reasons is why we’re not here. So leave a message, OK?

You Might Think: Mine is the funniest answering machine message this side of the Mississippi. My friends will love it.

The Employer Will Probably Think: Good lord, this person probably lives in Animal House. And I just can’t risk interviewing, let alone hiring, someone like Bluto or Flounder. Sorry, Charlie. Click.

3. Sending Your Resume and Cover Letter Without Proofreading

You Might Think: Everybody makes mistakes, even employers. So if there’s a mistake or two on my resume, no big deal. The employer probably won’t even notice, much less care.

The Employer Will Probably Think: Everybody makes mistakes, even employers. But making more than one minor mistake on a resume or in a cover letter is unacceptable, and often, even one is too many. How do I know this person will proofread the letters he writes to shareholders? What if he someday leaves a zero or two off one of our financial statements? I better put this resume aside and look for someone who’s more accurate and thorough.
