You need to understand the fundamentals first, if you don't you'll make the journey longer and harder than it needs to be. Firecode.io is fantastic from moving from 0 knowledge to being able to solve Leetcode Easy/Easy-Mediums. It focuses on repeating questions so you actually understand how to solve them. Getting the activation code takes a while because it's in beta but you can just DM the founder and they might help you get it quicker(that's what i did). Depending on how much time you have, you might want to "complete" firecode or once you've reached a decent competency with it (Level 3 upwards maybe) you can move onto more material. I'd recommend this site https://www.techinterviewhandbook.org/best-practice-questions/ It's basically just (most of) the questions from Blind 75. But it's given a 5 week schedule and more structure. If you attempt a question for a good amount of time and are making no process. Go on youtube and type "neetcode" + the problem name and there's a fantastic dude who explains the problems, concepts and solutions(in python). I have a copy of cracking the coding interview as well, but for that I write down the code on a notebook like you're supposed to. So basically: Understand the Fundamentals of Data Structures & Algorithms Firecode.io to get comfortable solving simple problems Cracking the Coding Interview or Blind 75 link i posted Elements of Programming Interviews (if you need more I guess) Answer from Dokrzz_ on reddit.com
