I've got 30+ years of programming experience and nearly 20 years of web app development experience, and I can't do these whiteboard interviews. They just don't work with the way my brain does. It doesn't matter how many projects I've worked on, how many clients made how much money from things I built for them, or how many people use my open source apps, all that matters is these humiliating stressful interview setups. I'm thinking about giving up on tech and switching to another line of work. It's genuinely breaking me, because I love coding. And I'm good at it.
