The problem with an unyielding, fairly uniform obsession with interview problems unrelated to actual day-to-day development is that you're institutionalizing Goodhart's Law. Eventually the interviews will encourage false positives as candidates grind on CTCI and LeetCode and pass interviews without actually being able to excel at actual work responsibilities.
I don’t think so. That’s why you’ll have candidates passing the questions but not the interview. We’re not looking got rote answers, we’re looking for comprehension, problem solving, and discussion.
It’s perfectly possible to drill and take preparatory courses to finesse communication skills specifically for answering and explaining whiteboarding algo/ds questions. These resources are perfectly aware that rote memorization is insufficient but being able to communicate is also required to game these interviews.
