Hi Vivek. I just got an email from Hackerrank checking in on why I haven't submitted any new code since the transition from InterviewStreet. I do not feel like it is a waste of time or energy, particularly since I use sites with problems as learning tools. For example, I used InterviewStreet for a few problems while playing with Clojure. But if I had good opportunities at the day job for hard-core hacking with Clojure, I may never have fished around looking for something like InterviewStreet. I don't care about the contest part but really like the problems from sites like yours. I do like seeing how many hackers have attempted vs successfully solved a problem. Can't remember if InterviewStreet did that. Rosalind (a bioinformatics problem/learning site) has a really nice "level" system and I'm guessing you have something similar setup for badges at Hackerrank. I very much like that you offer a variety of programming languages, but I might slightly prefer the Rosalind bioinformatics problems where you submit a solution within a time window rather than actual code to run. But it's cool since you don't force an "only python or ruby" language choice. Hackerrank's FAQ mentions building a community. I would participate much more if I thought the community of same language coders would offer feedback/code review and mentorship. I'd be willing to also give feedback on an anonymous basis. For example, say I solved challenge X in Clojure. I'd probably take time to review another successful solution for challenge X from another participant that also used Clojure - I would hope I could offer constructive feedback or learn how I could have solved the challenge better myself.
