Sure about that? The effort put into a leetcode medium or hard is usually way above the kind of code i’m mostly doing at work — and realistically i only have at most 2 hours a day of that level of work in me, the rest is the autopilot code, reviews meetings, docs etc.

I’ve found aoc/leetcode pretty much reversed the accidental atrophy for me

There is more to software engineering than solving code puzzles. What about debugging, writing clean code, writing effective tests, architecture, optimization, profiling etc.? None of these are exercised by doing leetcode. Use it or lose it.

Leetcode is about learning an algorithm/data structure. Programming in general is about much more than that. Knowing minimax and ring buffers doesn’t help much in knowing whether what your LLM does makes sense. For that you need to work on more open ended questions.
