- How is this different from LeetCode?
- LeetCode focuses on DSA. We focus on the rest of the interview: system design, behavioral, databases, networking, security, and more.
- Do I need an account?
- No account is required to practice. A free account lets you track submissions and progress, while Pro unlocks AI-powered grading, premium questions, and curated learning paths.
- Is DSA still enough for modern interviews?
- While DSA remains a common filter, the rise of memorization and cheating tools is pushing companies toward more creative, practical problems. We prepare you for both the traditional DSA roadmap and the design-focused challenges used by 90% of startups and quant firms today.
- How are answers graded?
- Written and code answers are graded by AI against a reference solution. You get a score, letter grade, and feedback.
- How are rankings calculated?
- We use a custom Elo rating system that adjusts based on problem difficulty and your performance history. This is combined with domain strength analysis, which evaluates your proficiency across specific topics like system design or security to provide a granular view of your interview readiness.
- Where do the questions come from?
- Questions are sourced from real interviews and curated by engineers. Anyone can contribute through the submission form.
