What is LeetCode?

Welcome to "LeetCode in Java: Algorithms Coding Interview Questions" course.

What is LeetCode?

LeetCode is a huge repository of real interview questions asked by the most popular tech industries( Google, Amazon, Facebook, Microsoft, Apple, Quora, LinkedIn, Bloomberg, Uber, Goldman Sachs, Twitter and more ).

Interviewers from the most popular companies(like Google, Amazon, Facebook, Uber, Twitter etc.) often directly ask questions they find on LeetCode. It's hard to navigate through the large amount of problems(around 1500) to most important questions, this is what this course stand for.I spent countless hours on LeetCode. From my experience, I'm telling you that you don't have to do the all problem and still be able to get a job at a big tech industry.

By the time you're finished with the course, you will be prepared for common technical coding interview questions.
