Hey Hii Ravi

How you doing dear.....Even i m working with a consultancy and faced the same sort of problem in the past....but there is one solution which helped me alot....be very aggresive in your approach and start early on monday as new resumes are there on monday and also handle the candidates with a dynamic approach...make them realise its them who needs the job change so they should comply....
things will improve for sure....
take care
