Don’t “Hire by Keyword”

After learning a few languages and paradigms, I find that I often have a 2 week ramp up for any given programming language.If you already know Java and Javascript, you'll get Scala / Kotlin in no time.
If you're experienced in Python and Django, RoR is a few weeks away.
If you're experienced in C++ and Python, it won't take long until you're good to Go.I get that companies want someone who's productive from Day 1, but they're missing out on a lot of great candidates that might only be productive from Day 15, but they'll be a lot more productive over time.
