Front end, back end, games, data science, embedded etc are all very similar if you ignore the frameworks existing in each domain. So you can become a decent generalist in all of them if you do it bottom-up and become fluent at relevant algorithms first, while if you go top-down and learn each framework then you will never become good at all of them at once since there is just too much complexity in each domains frameworks.

For example, a person who only knows react, angular, vue and node is a specialist and will unlikely be successfully to transfer to a different kind of team. A person who built their own javascript frameworks on the other hand had to build and learn a lot of fundamental concepts which are transferable to any domain, I could use such a person. So personally I strongly favor algorithmic interviews over more specialized ones. I don't care if you learned how to use library X to solve narrow problem Y, no matter how many times you did it.
