Please stop the coding challenges

one of the biggest problems with coding challenges for me is the conflict between providing a good solution versus making a strong impression.

do you show them a quick'n'dirty solution that ignores edge cases but shows i'm a pragmatic and not going to overcomplicate things?

OR

do you show something fancy that you'd never actually do in an real codebase that shows off my depth of knowledge and where my ceiling is?

Unfortunately, you often have to ask the interviewer (which is tough when it's a coding challenge and you have no way to ask for clarification on the rules). I know interviewers who will say "You didn't cover edge case A, B, and C, your solution is incomplete!" and other interviewers who will say "You are overthinking this, I'm just looking for an MVP."
