There are no cons which i could say for women to work at Misys. It was one of the best job environment i ever had with perfect balance of work and life. But i would again say being a product based company, pressure would be lesser in comparison with other service based..
It was a pleasant time and I have a lot of good memories and learning from Misys which has helped me in my career all through.
However, sometimes, the workload is quite high, but from my experience, it is the same everywhere.
