Having just advertised a (very) part time admin post I have been inundated by emails from people who have not read the ad properly, and it's taking up most of my working day answering them. Please, people:
If the advertisement says apply using the application form, don't email me your CV; that doesn't constitute applying, and I won't read it.
There's a reason I didn't attach my phone number to the advertisement; don't expect me to be available to talk to you on the telephone.
For god's sake don't send me an email with a naff graphic across the bottom of a hipster crowd-surfing; it gives me the impression you're a waster.
If the adrvertisement says high level of literacy required, don't send me an email in txt spk.
It's usually a good idea not to irritate your potential boss at the first interaction by sending a series of emails that indicate you can't read a basic form and require your potential boss to download something for you that you could easily find yourself.

Any more gems?
