Exactly!
I'm often the only female in the IT departments I work in and its been this way since I started in 1998. Working for small companies is my preference because they are more selective in choosing who they hire so no one questions why they brought in a female. When I take positions at large corporations, everyone immediately thinks I'm there to fill a quota and is always shocked that I'm competent. That bothers me. Even worse, I know I have been hired at least once to fill a quota. The money was right and there was opportunity for growth so I just shut up and took the job.
Five years ago, my management was trying to force me into management because I was female. I had to fight and almost quit to make them realize I had no intention of heading into management yet.
I know of a 50 year old white male that just got laid off because he was too white and too male. He has 30 years of industry experience. He was told there were too many supervisors on his team and his position was being eliminated completely. Before he had even packed his coffee cup, a 30 year old Asian female with 2 years of experience was PROMOTED to his position. So much for it being eliminated.
