People Don't Turn Up To Join After Getting Offer Letter

yes, as Aussie John said, you can only mitigate the problem but not completely eliminate it, given the inability of human nature to resist the temptation of searching always for pastures looking or appearing greener on the other side.The best way to approach the problem is to accept it as a professional hazard and gear yourself up to mitigate the chances of putting up 'no-shows' by candidates instead of expecting an ideal situation where every candidate that is selected joins the job.

Hello Chaitanya,
Below are critical aspects of an HR Interviewer which are neglected / missed by many currently.
* Understand why the candidate is moving out from his/her current organization
* Understand what drives the candidate to join your company
* Urgency to close the position and notice period candidate needs to serve to join your organization
* Salary fitment and offer rollout - explaining the offer letter clauses and salary annexure [income / deductions]
* Evaluate the authenticity of the information candidate shares during the interview
In addition to this, the recruiter must be in touch with the candidate to sense any drop out possibilities.
In other words, recruitment is not procurement of people. It involves a lot more of experience and expertise.

I would like to add the following point:
I believe, an offer becomes a contract when parties of the offer sign the document. Therefore, once the offer letter has been signed by the candidate in physical and the HR, it is a contract as per law. HR can initiate the proceeding against the candidate if do not joins.
Please add to it, if it is feasible.
