I was called by a consultant. They took 3 interviews (all face to face interviews). After the process was over, they told me that I was selected and asked for my last months salary slip and other related documents. But they never gave an offer. Kept waiting for months. They should understand , that if they do not want to hire for an approved vacancy, they should not waste candidates time for coming for face to face interviews. Lot of times, candidate has to take leave from current employer for coming to interviews.
