Seriously. It's hard just finding a job as a generalist developer, or even a "full-stack web & app developer" without every interviewer asking "so...backend or front-end?"
Me: "Whatever helps bring value to the customer. I've done it all and [gives examples]"
Them: "We have a frontend role and a backend role. Which do you want?"
I consider myself a generalist, and if I had to choose, it would be backend. It's more low level and fun, and honestly, I'm not a great designer. The point of being a generalist is that you can adapt to more places.
