In the past few weeks, I've seen a ridiculous amount of resumes. From friends, contacts, job applicants, and lots of other people in between and almost without exception - and I mean this with the best heart possible - they suck.

Some are misleading and/or false.  I know someone who lists his college experience starting from when he were accepted and ending when he failed out.  Conveniently enough, this is four years... while it's not an outright lie, it certainly does imply that he has a degree.

No, I'm talking about the quality of the resume itself.  While I'm not a resume pro, I've been interviewing more and more candidates in the past few years and I know what annoys and appeals me.

First, read your resume.  Does it make sense?  Is there anything that makes you stop and re-read the line to understand it?  If so, re-write it.  Clarity never hurts.

Next, what about the grammar and spelling?  Are your verb tenses correct?  I'd wager that almost everything on your resume happened in the past.  ;)  Have you run it through a spell checker?  I expect a few spelling errors on blogs just due to their transitory and time-sensitive nature.  Your resume is not the same.
