I have had already given the interview in virtusa at wagle branch. i was selected for this profile. one of the Hr name anushree took my all documents online and said that ur joining date has been postponed. after one month i called her to ask about my joining, she said i have ur offer letter but i cannot tell you fix about your joining. I also asked her to mail me the joining letter but she did'nt mailed. I wasted almost 2 months and ended up with nothing. Worst management !
