The problem with realistic work-sample problems is that most of the difficulty in real life programming comes from complexity which cannot be replicated in a 1 hour technical interview. You can't really test someone on their ability to add a feature to a 10 million line code base that interacts with 50 different other modules in an interview setting. A 1 hour technical interview is going be either realistic but trivial and useless for differentiating candidates, or difficult through contrived means (like leetcode).
