Ericsson BNet R&D is a nice place to work and I don't think I saw any bias till the time I was there.
I joined as a Communications Specialist in 2013, I personally had trouble working there as I felt I wasn't learning enough and was fearful of stagnating early in my career. On the R&D front, the managers are usually nice and there's enough opportunity to grow.
Though it differs from project to project. Some of my female friends are very happy with their managers, some are not.
Pros - It is reputed company.
-The company has women policies in place.
-The environment is good.
-One of the best in telecom.
Cons - Telecom is a male dominated domain.
Females have to prove themselves everyday.
Being asked to work on weekends. ( Again it depends on the project.)
