It's sad how a lot of people see this as "a bad way to test job candidates" rather than a "fun way to practice ML skills".
But thanks for giving Leetcode yet another idea to test AI Engineers who do not know how to write a multi-layered perceptron or a softmax activation function from scratch with yet another repository of already solved puzzles to making it easier for interviewers. I'd say its pretty useful myself.
And so it begins with the complaints of "The AI interview is broken", "We are the only industry that does this" frequently being preached here.
