Reading this just made me question why there isn't a shift from typical leetcode style interviews to interviews where you're asked to do do things like find places to optimise code from a tiny toy app and debug it etc. It seems like an almost universally useful skill and even with people trying to "game" such interviews, it would produce good engineers who know how to optimise what they write. I have read accounts of such interviews happening, but from my (limited, so feel free to correct me) knowledge, they're certainly not the norm.
