Went for an interview they said I have got selected while interview, but they didn't give me the offer...very disappointed... I have gone through 5 rounds of interview so I was hoping Soo much that I will get an offer... They finally said director was not happy to proceed with you .. he is one said to me that we can proceed further at the time of interview.. don't know whether they have requirement really or not.. it's very disappointing after attended Soo many rounds and said no... very big process for interview but no use... Don't know what's thier strategy on it , but it's completely time wasting and same thing happened to one of my frnd after my enquiry so may be this is use to for this company to do time waste for the people in the name of interviews... Very dissatisfied with the exp I have...
