I actually never heard of Leetcode before this thread but I highly doubt that. This seems to be a puzzle site like Codewars or Codingame. While puzzles like that are fun, they are only one small part of being a developer. Design, architecture, UI/UX and communication are a lot more valuable than being able to write your own Sudoku Solver.
