Not just that. Engineers get pigeonholed into tech stacks as well. It's almost as if companies (recruiters, really) think a senior engineer can't learn another programming language or something. They come at you with "we're looking for someone with strong golang experience," when there's no way to get "strong golang experience" without working someplace that uses it.

Learning takes time

And? There's a learning curve any time one starts a new job with a new code base. Do you think a senior engineer can't become productive in a new codebase with a new language in a couple of months? If so, I'm going to guess you've never worked with a good senior engineer.

The time it takes to learn a new language, especially a typical one like Go, is insignificant on a project lasting more than a couple weeks.
