Maybe it's just me, but I want people that are reasonably competent and you can work with. Maybe there are some jobs that require deep understanding of maths/proofs etc, but those are what, maybe 1 in 100 engineering jobs?

More often than not a deep interest in a particular technical domain is a liability. It's like that guy that insists on functional programming design patterns that insists on a fold with tail recursion where simple mutation could have easily sufficed. Or endless optimization, abstraction and forced patterns. Bro, you're working on building a crud app, we don't need spacecraft design.

The math puzzles like this are supposed to show deep mastery. I assure you that you don’t need DP in 99.999% if cases as well, but idiots are still asking house robber.
