For me, ive always been a fan of the classy C.V and cover letter, in an envelope with a printed address. If they say post or e-mail, send it by e-mail, otherwise you look like you have problems with e-mailing.
I think the part which seals it is a mission statement or personal statement. Throw in words such as "hard working" "enthusiastic" "driven" "motivated" "personable" and wont go far wrong. There are a host of free online cv designs.
I also agree with the
[email protected] email, anything else just looks shady.
At interviews i always make sure to be very nice or friendly to the staff at the company, obviously the interviewers but also the others i.e receptionist etc, as they all have a say in who is hired in a round about way. I turn up 10 mins early and make sure i am uber polite, say something like "lovely building" or "nice staff" and always very politely decline any offer of tea etc. as its a pleasantry they dont actually mean.
I always ask a question, well worked out beforehand, and have a good long look at their website, know the company etc beforehand, and find something, a report, website design, advertising, company aim etc to compliment them on, something a little unusual.
I always wait 3 seconds after a question, look down then up, and then reply. Gives me the air of a thinking man.
In the Art of War, Sun Tzu said, "You have to believe in yourself" which i take to mean no negativity at all in an interview, but remaining modest at all times.
Anyway, thats what I do.
