Flasheart and hora – I would have thought before i worked in recruitment that you were right. However, if it’s a reputable agency (okay, there are a few) and have a good relationship with their client, then you may well shoot yourself in the foot by going direct (their client might be using an agency so they don’t get applications direct, which may get lost). Don’t play games, most recruitment folk are pretty useless so ring them and ensure that they put you forward. Play games and p1ss them off and remember that they are holding the cards – I don’t do anything immoral because I like my sleep but I could still cause someone considerable pain if I wanted. Some of the people I know in recruitment don’t care about anyone so they’ll do all they can to screw you over.
Summary – one application, make sure you follow up with phone call, convince them you’re great. One thing to remember – they have to state the client’s name before they send your CV – DTI regulations – so you will know anyhow.
