I am considering leaving tech because selective biases play a larger role in hiring and advancement than they used to despite all efforts to the contrary. After talking with other people I am not alone in thinking this. I am willing to leave tech even though I cannot afford to because the hit to my finances is temporary but the barriers to my career from remaining in tech are permanent.
Let me discuss selective bias in a bit more detail. When I first started programming candidate qualification was centered around the needs to the business. For example, did a candidate understand the minimum criteria of working in a given technology plus the advanced criteria that harmed user interaction, slowed execution speed, or some other measurable concern. Those days are long gone, at least in high level languages.
Now the name of the game is programming fashion. Specifically, does the candidate write code according to a current trend a given team or interviewer wants without regard for any performance or measurable quantum.
That change is disruptive but not in a healthy way. In the old days the desirable and rewarded developers were those who performed well, such as writing the best code in the least time. The people on the right side of a bell curve. Replacing that with fashionable and non-measurable factors limits candidate selection to the center of the bell curve, which are people who do not perform as well but are better rewarded for it.
If I am willing to abandon a long time tech career even though it will hurt and have found others that share my frustration I can only imagine that perhaps this might be some small factor in why some women might want to leave in general.
I suspect this problem has increased despite all efforts to the contrary because all efforts to eliminate hiring/reward bias were typically limited to identity factors that carried provable legal consequences.
