It really depends where you’re working. Companies like FB, Google, and Amazon need to test programmers on data structures because certain structures work better in certain situations, and when their software engineers know which tools to use to optimize a process to run in 5μs instead of 10μs... well, let’s just say for a company running tens or hundreds of thousands of servers, every microsecond saved means less servers the company needs running. And less servers = more $$$.

But for most startups or mid sized companies it’s way more important that developers know how to get shit up and running, and less important the actual code they write to get there.

The problem is a lot of smaller tech companies look up to companies like Google and try to copy they’re interview process because hey, it’s Google. And these companies never consider that just maybe an app with billions of users has a slightly different set of requirements than their app with 500 users.
