I've worked on a number of teams that were all male - other than me, of course. In some cases, I had no issues related to the fact that I'm female. In other cases, I encountered males who assumed that I was incapable of performing the job, simply because I was female - and told me so. And even when I proved myself as capable as them - or more - I was constantly challenged/tested verbally on my technical capabilities
in ways that the males were not. A few people continually told me that I was hired/retained/promoted simply because I was female. . .even after I had proven myself to be as capable - or more - than they.
That's quite a mental/emotion drain that males on all/predominantly male teams don't face - at least regarding their gender. And since all/predominantly female teams are rare in tech, it's a situation that male techies will rarely, if ever face, or even need to contemplate - at least regarding their gender.
So, I would be curious because I would wonder if I might encounter sexism on the team - sexism at a level that would drain/distract me. Well, I never let it distract me, but it was certainly draining.
