My biggest concern about Leetcode is that it’s not actually that relevent to the day to day job of being a software engineer and has more to do with being a computer scientist which is an adjacent but different set of skills. I’ve worked mainly on scientific software which requires a mix of domain knowledge and programming skills. I doubt many people who I’ve worked with would pass leetcode without spending a lot of time studying, because they primarily come from Physics/Engineering backgrounds, but that doesn’t mean that they are not good software engineers, that the software they’re writing is not performant, or that they can’t offer anything valuable.
