It's too pathetic to explain because thinking the day of interview itself is irritating. The HR process is worst with this company, they made me sit for four long hours to take the first round of interview. And to my surprise I met a few friends working there and they had very bad reviews of the company and its HR. I heard they did not get confirmation letters even after months and there were hardly anyone to assist them in the night shift. Sorry to say but guys please inquire thoroughly before getting into these kind of environments.
