SexyLady@aol.com need not apply
Another "duh" tip. Today, we all have at least one email address, Twitter handle, Facebook name, or LinkedIn ID. Your resume should absolutely contain at least one of these -- likely more -- but not if you have inappropriate addresses or handles.
Daphne Alvarado, SPHR, noted, "Don't use a personal email address like email@example.com or something along those lines. Take the five minutes to set up an appropriate email address. I can't take you seriously if I see something like this on a resume."
Well said and pretty obvious, but it would seem that too few people are thinking this through.
