Well, all the platforms almost are same except the interface. That's what I think. To conclude the result, let's compare them through the features they offer. Features of Leetcode - Topic - wise questions Comapny-wise questions Weekly contests Interview Preparation section Discuss section Features of HackerEarth Topic-wise problems Monthly contests Discuss section Hiring Contests Hackathons Earlier, when I started coding in my first year. I was fond of HackerEarth. But when I stoped using hackerearth and shifted to Leetcode, I like it more. It depends upon how much comfortable you are with the interface. But, it can't be denied that Leetcode offer more than HackerEarth. But for the coders who love hackathons, HackerEarth is best for them and for the people looking out for job opportunities.
