I know of an employer that employs asian females almost exclusively in their production area. The job is mostly soldering through hole components. The pay isn't very high.

It really seems like race based hiring practices.

I’m a 35-year-old in Seattle, and I’m genuinely terrified that I’m already becoming too old for this industry. I looked around our all-hands meeting yesterday and realized that except for upper management, almost everyone on the engineering team is fresh out of college age.

Our CIO is pushing us to learn a programming language that no one has heard of. He used it in his old job. One looked into it and found that no company or government agency in my state used it.
