Are there people out there who only want to work in one language or be hired explicitly for one language? On the other side are there employers who only want people well versed in X language?<p>I guess what I'm getting at is: most great developers I've met choose and use whatever language is the best fit for the job, even if it isn't their favorite. Targeting a specific language appears to be more of a niche, to me, and not as forward-thinking (what if, in order to scale, a different language is more appropriate and you hired only Python experts?). So how typical is it for people to go through either side of this type of process when you're targeting for a very, very specific type of knowledge ?<p>Curious mostly; not trying to simply be contrarian.
