Everybody wants to hire that one person that's crazy about software engineering and will transfer the way team works and tremendously improve product's architecture. While I've worked with such people, they're rare, so most companies settle for people who can just competently deliver without being a crazy trailblazer. What is important is following the latest popular technology trends though - there's never enough people on the market who know these, so if you know them, you're good. Also probably leetcode/whiteboarding if you're in the US, but I can't speak much to that cause I'm in Europe and it's rarely practiced here.
