I've been in charge of hiring a few jobs now and I make sure to not care about any of the typical signals when interviewing. I tell recruiters and candidates alike that I'd "hire three raccoons in a trenchcoat if they could turn requirements into working code".

I've hired quite a few folks who didn't fit the typical mold, because they could write some sweet code. Who cares about eye contact, I want honest, hard working problem-solvers.

The biggest thing my less social folks struggle with (for anyone curious) is requirements gathering. That often takes interviews and repeated interactions with customers. But it's a skill like any other. Practice brings improvement!
