Dear Srinivas,No Shows are very common in this corporate industry. We cannot completely stop this, but yes we can prevent it.First don’t believe in what ever candidate says. Try to understand his pulse.Check how genuinely he is looking for a change. Candidates will post their resumes for various reasons such as- to check the market trends, to know their technical expertise, some may be looking for a job genuinely... So the recruiter should cross question the candidates to get truth out of them likeWhat is the reason for his job change?He/She is married? Will he/She relocate with their family or will their family does not have any objection to relocate.What is present company's notice period? He has some bonds? If they have any notice buy out option? ...Using this try to judge the candidate, now the guys are smart they will have ready made answers, but we don’t have any option.Do the follow up properly after selection with the candidate, if you find him/her fishy just tell your apprehension to the client about the candidate and try to give replacement immediately.We cannot help if the candidate is getting a better offer at the 11th Hour and joining the other company.These are my Suggestions hope it will help you.Regards,Anil Kumar M.KTeam Lead-Resource ManagementASAP Info systems Pvt.Ltd
