I always find reed.co.uk is quite good in that there are a lot of agencies working through it. I never put personal details (like address, phone and even name) on as howlie says it can be dodgy.
good luck
If you located in India, I can refer you the ‘submit resume’. It is one top job portal website in India providing all the information about job seeker and employer details. For more info visit their website at http://www.submitresume.in/.
