Become slave is the biggest benefit.
No Job security.
Working on festivals(Its holiday but you have to work because, if you ask leave that day your manager will ask you, what should I tell to client).
Don't ask anything work like slave, if you work more 11 or 12 hours per day you are good employ[Its the management feeling] else you are not right person. How much good work providing to them they wont look that, they will look only more than 12 hours per day.
No job guarantee, They will pay very less and lot of restrictions.
Once you enter the office don't turn your head, if you turn more than 2 min, you will get call from DIRECTOR, why you turned? I will tell the reason, then other person phone will ring.
From your salary they will take some money, they will tel you we will pay to you when you finish the year, mostly you wont get. I did not get huge money, I worked more than 1 year. So I left.
Don`t join this company, If you want to become as slave then join here and forget your personal life. Mostly you have to work 7 days per week. per day more than 10 hours and 6 working days.
