How It Works

Three steps to your best interview performance

1
1

Configure Your Interview

Choose difficulty (Easy, Medium, Hard, or Mixed), set the question count (up to 5, depending on difficulty), and optionally focus on specific algorithm topics.

2
2

Solve & Discuss

Write solutions in the Monaco editor, run against test cases, ask the AI interviewer for hints, and submit when ready. 3 attempts per question.

Review Your Performance

Get an overall score, per-question breakdown, complexity analysis, and targeted feedback on exactly what to improve for your next interview.

Good approach using two pointers! Can you tell me why you move the pointer with the smaller height instead of the larger one? Think about what determines the water volume...

Everything You Need to Succeed

A complete interview simulation environment - no setup required

AI-Generated Questions

Every interview is unique. Claude generates fresh, relevant DSA problems tailored to your chosen difficulty and topics - no repetition.

AI Interviewer Chat

Stuck on a problem? Chat with our AI interviewer for hints, clarifications, and guidance - just like a real technical screener would.

Monaco Code Editor

Write solutions in Python, JavaScript, TypeScript, Java, C++, or Go - with full syntax highlighting, autocomplete, and keyboard shortcuts.

Instant AI Evaluation

Submit your code and receive a detailed score, correctness rating, complexity analysis, model answers, and actionable improvements in seconds.

Smart Hints System

Progressive hints reveal approach, edge cases, and complexity hints without spoiling the solution - perfect for building problem-solving intuition.

Performance Analytics

Track your scores across sessions. See your strengths, identify weak topics, and review model answers to accelerate improvement.

Difficulty Levels

Choose a level that matches where you are in your preparation

Easy
Up to 5 questions · ~10 min per question

Fundamental patterns and core algorithms. Perfect for warming up or building problem-solving intuition from scratch.

Medium
Up to 4 questions · ~15 min per question

Multi-step problems requiring deeper reasoning, edge case handling, and optimization trade-offs.

Hard
Up to 3 questions · ~20 min per question

Complex, FAANG-level problems. Strict evaluation on correctness, complexity, and code quality. Expect deep follow-up questions.

Mixed
Up to 4 questions · ~12 min per question avg

A curated blend of Easy, Medium, and Hard problems - simulates a real interview where difficulty ramps unpredictably.

Pro Interview Tip
For each pattern, be ready to explain: (1) what problem it solves, (2) time & space complexity, (3) when NOT to use it, and (4) a concrete example from your experience or practice. Interviewers value the "why" over the "how".

Stop Rehearsing. Start Performing.

Every session is timed, unique, and graded - just like the real thing. Configure your difficulty, solve problems with an AI interviewer at your side, and walk away with a score and model answers you can learn from.
