Coding is not the only thing required to be an excellent developer and contributor to your team and company. Sometimes you must gather requirements from users / customers. Sometimes you have to work with other teams or products to integrate them into your product.

There’s also the aspect of working with the rest of your team on whatever problems you are solving and not siloing yourself to just the problems you’re working on.

That and when you’re hit with new and interesting problems that have never been solved before, you cannot look those up in the leetcode manual and memorize them to solve. You have to actually create something on your own and apply whatever you’ve learned from programming in the past.

It’s like playing a survival video game with the detailed how-to always at your fingertips versus being in the wilderness having to survive on your own wits without a guide.
