Unfortunately the leetcode whiteboard interviewing strongly encourages this type. Even almost requires it. If all energy is spent on that, it is time not spent learning how to build stable products which can be maintained long term. Because turns out that popping out algorithm exercise code after another into source control doesn't produce a good product. But that's what current interview fad measures, thus it's what it produces.
