I couldn't speak to careers, but my curiosity was enough for me to ask a biochemist to join his bioinformatics class despite lacking a great many prerequisites.

I was quite helpful to him and the other students (who mostly struggled with packaging: conda, pip, apt, etc). In turn, they were quite patient with my lack of biochemistry background. It was nice to get a taste without having to take what would've been 2.5 years worth of prerequisites.
