At times some people in the HR Department of certain companies conduct the BGV process with an eye of suspicion only. When a fairly experienced candidate mentions in his C.V about two or more companies in which he had already worked and attaches relevant documents and during the BGV conducted if one company does not respond or could not be contacted by the prospective employer, it is not the fault of the candidate. In such a situation, professional reasonableness is required on the part of the HR. What about your membership with EPFO?If you have got the A/C slips from your enrollment in the first Company, it is a corroboration of your service with it. Better make a representation to the Head, HR and explain the hardship being faced by the poster as he already left the last organization in anticipation of the appointment with WIPRO. If it is of no use send a legal notice claimimg damages for not implementing their offer.
