A Few (Free) Learning Resources

1

LeetCode

4) LeetCode- they call themselves “the best platform to help you enhance your skills, expand your knowledge and prepare for technical interviews.” LeetCode has 2000+ practice questions which range in difficulty, so if you need to brush up on those data structures and algorithms, this is a good place to do it. They support a variety of different languages so you can practice in whichever you prefer. They also run contests where you can earn points, and their discussion boards are pretty good.

Edabit

6) Edabit- this platform is fairly new, I believe. I discovered it about a year ago. As a super newbie, I was looking for something less intimidating than Codewars or LeetCode. Edabit answered the call. They boast 10,000+ interactive, “bite-sized” challenges. What I like most about them was after completing a problem they’ll ask you if you found it easy or challenging and based on your answer will give more problems at the same level if you had trouble or start advancing the difficulty if you breezed through the previous problem. I would call them very beginner friendly.

CodeSignal

7) Code Signal- this one was suggested to me by a bootcamp instructor, so of course I needed to check it out. The Code Signal platform is “skills-based assessment platform.” They also have a good practice section that is set up like a game. You practice in the Arcade, get points but solving challenges, can use your points to unlock other features, and it shows you a grid much like Github that lights up your activity to motivate you! There is also a section to help prepare for technical interviews with commonly asked data structure and algorithm questions.
