It is not about women. There are no ethics problems particularly. Espire Infolabs is not very employee friendly.
Pro -- They give you a job if you have no other choice in NCR. If you are waiting for a better offer, join in the meanwhile and search outside.
Cons -- 1. Salary is never on time. If you are a PM level, please make sure you have financial back up because if the salary arrives, it might get paid in parts to you.

2. If the company loses the project you work in, you do not go on bench. They simply fire you.
3. In Gurgaon office, there is no cafeteria / means of food at all. If you do not get your own food and feel hungry at an odd hour, you might end up staying hungry or walk up to the Nokia office nearbuy.
4. Since it is a small company, dependency on a few people is expected. These few people (since they are in good position) will talk you down like shit and it almost seems you are asking them favors when you are actually demanding your rights.

For women and men it's equally good. Any organization's culture mainly depends on its employees too and leadership. It will surely be a learning experience for you since possibility is you will get added responsibilities in the times to come.
