As an alternative to Leetcode, I have had a good experience with Byteboard. It's sort of a "project" based interview format, that comes with 2 parts.
Part 1 is a design doc where a problem statement has been outlined with goals and notes from the development team. Your job is to respond to their questions and propose a high level architecture to solve the problem. Part 2 is the coding portion, you're dropped into a codebase that relates to the previous portion and are given a todo list of tasks to complete. It's basically feature implementation, ranging from trivial to somewhat involved.
I really like this approach. As someone who has interviewed a lot of candidates using Leetcode style questions, I would love if my org moved towards this format. Unfortunately, it's pretty hard getting FAANG companies to drastically change hiring practices, but if smaller companies start adopting it maybe it will get some traction.
