How would you describe the difference between SoloLearn and HackerRank?

Question

I'm just starting to use them and wonder which are their pros and cons as well as other people experiences.

Answer 1

I tried using HackerRank, SoloLearn is more new-people-friendly and HackerRank is more like someone who already has a basic knowledge in programming, I didn't use HackerRank that long due to I'm using Android and its uncomfortable visiting that site again and again

Answer 2

SL is more for beginners while HackerRank is more for professionals. You need a CS degree to understand some of the challenges on HackerRank.
