Everyone is very pleasant during the interview,
but the salary they offer is very, very, very low.
Overtime is your own business and has nothing to do with the company.
You also have to cooperate by going out to hold lectures and events on holidays; you only get compensatory leave and no overtime pay, and you will be humiliated even when you take the leave.
Every Friday, they clock you out punctually at the end of working hours, even if you have not finished work.
