Something I have just learned:

A lot of people see no problem with saving their CV as just "CV", and send it as an attachment when applying for a job.

 

I'm looking to grab two people for one- or two-day temp work here, just envelope stuffing.  After the third "CV.doc" attachment, I have decided to just stop downloading those.  If you can't be bothered to save your CV as something vaguely close to unique, I can't be bothered to look at it.
