I just got a job with a technology stack I knew very little of (scientific computing and image processing). It's definitely possible.
I'm not saying companies don't want people to know specific technologies, nor am I saying you shouldn't learn them. Just that most programmers undervalue a whole bunch of skills that companies actually do need... and if you present yourself right the company will say "oh huh that sounds useful" even if they didn't think about in the first place.
Good template: "I identified problem X, solved it with technology Z, and saved the company Y money/year". Demonstrates not just doing what you're told, but a specific skill (identifying problems) and resulting consequences.
Another good template: "I identified problem X, investigated, chose technology X, with result Y." Demonstrates you're a quick learner, identify problems, not limited to current tech stack.
