Let it suffice to say that Linux distributions (and some closed OSes) try very hard to prevent package fragmentation.
Experience has shown many times that excessive fragmentation leads to proliferation of unmaintained libraries.
Node is quite bad - it encourages a proliferation of small libraries and remove the needs to move the versions forward. This, in turn, leads to a wasteland of old, unsecure, dependencies in the long them.
Ex Amazon here. I've done a lot of interviews and I've never seen candidates being refused an on-site interview for having extensive Windows experience.
Still, the hire rate would be really low. Most would have little knowledge of what exists outside of an IDE: OS internals, system design, networking.
