Certainly not, more just coincidence. I believe we made offers to men through GA but they had already lined up positions.
However, depending on the class they can be pretty close to even on women to men. 2 of 3 hiring events i've been to in the last year were half men/women, one i'm pretty sure was more women then men (7/4? something like that) but that was in Boston at specific time so YMMV.
Do you have some sort of explicit gender-based filtering in your hiring or recruiting process?
