I had joined PSL at very senior position and was a pioneer member of their product division now spun off as Accelerite. I can give general inputs about PSL but like all organization the culture and other details are based on teams that you work for and overall Business unit charter as you might understand.
PSL has good policies wrt Women and have seen healthy workforce ratio which goes to suggest that its women friendly organization in general. I have personally lead Anti harassment initiatives in PSL. I also know they have very supportive policies for women who take time off for maternity reasons and give up to a year of support under their policy.
In general good place but Work from Home is not the culture, not many women at mid management and at the top, typical services organization and mentality which is way different from product organization and thus could be a fitment issue for some who have not had exposure to services organization. Pune and other centers have better facilities then in Bangalore in general however Bangalore is not substandard compared to most companies ie its competitive enough.
