My experience of cracking coding interviews (2018)

1

LeetCode

Leetcode.com - My favorite portal for interview preparations. The best thing about this is you find lot of intuitive, unique and easy solutions. Everyone solves a problem in different approaches, there you see all those solutions. Also, it has system design, database design questions too. Have a look at it.

GeeksforGeeks

Geeksforgeeks.org - A famous computer science portal having everything you need for interview preparation. But in my opinion, the code, methods are not too intuitive and simple, their code has some bugs too. For example, consider this problem, http://bit.do/PetrolPump , the solution is not too intuitive. If you see this solution : http://bit.do/LeetcodePetrolPump. It’s very easy. That’s why I recommend leetcode over G4G.
