🧠 Exploring coding challenge platforms — which ones actually help you grow as a developer?
https://www.reddit.com/r/programming/comments/1oixvcn/exploring_coding_challenge_platforms_which_ones/
<!-- SC_OFF -->Hey folks, Over the past few weeks, I’ve been exploring various coding challenge platforms to understand how they differ — not just in problem sets, but also in how they impact real skill growth for developers. Some focus on interview-style DSA questions, others emphasize language mastery or competitive programming, and a few even encourage collaboration and discussion. I put together a short write-up summarizing what I found useful (and not so useful) across popular platforms — from LeetCode to Codeforces, HackerRank, and others. Sharing it here in case anyone’s interested in comparing experiences or adding platforms I missed:
🔗 Best Coding Challenge Platforms: LeetCode, HackerRank & More (https://sagarnikam123.github.io/posts/best-coding-challenge-platforms/) I’m curious — for those who actively use challenge sites,
👉 Which platform do you feel provides the best long-term learning value?
👉 And which ones are overrated or just “grind traps”? Would love to hear your thoughts — especially from those mentoring juniors or hiring devs who use these platforms regularly. <!-- SC_ON --> submitted by /u/sagarnikam123 (https://www.reddit.com/user/sagarnikam123)
