Also, keep in mind that not all "mistakes" on a CV are intentional, or lies, or for self-marketing. Nevertheless, they can still come back to bite you. The safest bet, therefore, is to treat it like a "sacred" document, and go back over it with the same detail you would for any important form (tax, loan application, etc.) Of course, make sure your degrees are accurate (with accurate dates), but also, if you are listing conferences, publications, workshops, WHATEVER that you attended/presented, go back and find the program or hard-copy of the materials to make sure the date and such are accurate. Don't just "guess" or assume it is correct. ALSO, don't necessarily trust what you are told by conference organizers or editors; FIND THE HARD COPY. I got into trouble with this once when applying for my first job because I didn't have the conference program in front of me, and typed "march" instead of "may." Later, I got the program, but just forgot to fix it. Obviously, it wasn't "lying" because I did the conference, it was just a hasty mistake that I shouldn't have listed until I had the program in front of me. People WILL check on things, and even though it's an easy "fix," it's an embarrassment to have someone call you and say, "Um, there wasn't even a conference in March, dude." I DID have someone call me, and I had to provide documentation. Easy fix, again, but still embarrassing because it makes you look foolish and unprofessional. Going back over every element of your CV to check for those details is useful. Again, do it just like you would an important application. You wouldn't just write your address randomly or your age, or just "guess" your date of birth. Nobody ever really teaches you how to write or how to "treat" a CV. All the way through undergrad, grad, and even my doctoral program, everybody kept saying "do your CV" and yet NOBODY ever said how you go about doing one, and what the "priorities" should be in terms of checking all the details. Learn from our mistakes, and go back through it all with a fine-tooth'd comb.
