Monster.com is the worst recruitment tool that you could ever possibly want to have. The only applications that i have received for the multitude of jobs posted are random applications from India when the job is in the UK.
They dont have an up to date searching database - they dont advertise thier company and so there is no up to date traffic that they attract. They will blind you with promises of extra things to attract candidates that possibly would work but they dont have the traffic and so its a non starter no matter what they offer.
They will tie you into a contract that you cant get out of and will provide nothing of use.
In a nutshell, they are bloody awful... STAY AWAY
