THBS is a great place to work and there won't be any issues for women. As per my experience, my whole team used to respect women and was friendly.
But one thing like any other company, even it has few politics which depends on us that how we handle it.
THBS has been a typical service setup and very strict on timings and even endless work hours if the project so demands. Invariably thbs bags projects with tight deadlines, hence developers/testers usually struggle. The management layer wasn't competent then and very biased with their coterie.
