LeetCode vs HackerRank — which to use in 2026.
TL;DR
LeetCode wins for candidate-side coding prep (2,500+ problems, active discuss forum). HackerRank wins for employer screens and SQL. Neither covers system design, behavioral, or mock interviews — which is why many engineers supplement with Alpha Code ($19/mo, all-in).

Frequently asked questions
- LeetCode vs HackerRank — which is better for interview prep?
- LeetCode is better for candidates preparing for FAANG-style coding loops; HackerRank is better for taking employer-required screens and SQL challenges. Many candidates use both.
- Is LeetCode more difficult than HackerRank?
- At the upper end, yes. LeetCode Hard problems map to the hardest FAANG rounds. HackerRank problems skew easier but are more representative of first-round screens.
- Which has better SQL coverage?
- HackerRank's SQL track is broader and widely used by employers. LeetCode's SQL section is smaller but maps to FAANG SQL rounds.
- Is HackerRank free and LeetCode paid?
- HackerRank is free for candidates. LeetCode has a free tier and a Premium tier at $35/mo that unlocks company-tagged problems and SQL+.
- What's the alternative to both?
- Alpha Code is a patterns-first alternative at $19/mo that replaces LeetCode + HackerRank + separate system-design, behavioral, and mock-interview subscriptions.
