"Companies look for talented software developers"

While that may be true, and it's what they all say, ultimately they just filter on keywords.

Of course, if you have a network then that's less of a problem. You are talking to a real person who can evaluate you.

If you don't it doesn't matter how good you think you are, you are at the mercy of the filters. It's not about your ability to change stacks, or your ability in general, it's about how companies select people.
