Practice the interview rounds LeetCode skips.
Carry a case from clarify to build, with an AI interviewer that reacts as you work. Built for intern and new-grad SWE and DE loops.
You drilled puzzles.
They tested the job.
You solved hundreds of LeetCode problems. Then the interview opened a real codebase and asked you to find the bug, or handed you an ambiguous system to scope.
What you practiced
- Reverse a binary tree
- Two Sum
- Sliding-window maximum
What they actually ask
- Fix a failing test in a real codebase
- Scope a vague, real-world system
- Ship a feature without breaking the build
Closing that gap is the entire product.
See a real Case LabTell us where you're interviewing. We build the plan.
Pick your target company and role. We map the rounds they actually run, then turn them into a week-by-week plan. It draws on the same real-question library behind our Case Labs.
- Week 1Scope ambiguous problems
- Week 2Design under real constraints
- Week 3Fix failing tests in a real repo
- Week 4Run the full timed loop
How our AI grades you
Real Interview Scoring
What you're evaluated on
The goal: Can you solve problems, explain your thinking, and write clean code?
Every format. One feedback loop.
From raw algorithm optimization to full FAANG loops. Click any node to explore the journey, then drill into each format below.
DSA Patterns
Master 15+ core algorithmic patterns. From Sliding Windows to Advanced Graphs, learn to recognize patterns rather than memorizing problems.
- Pattern recognition practice
- Time & space complexity analysis
- Progressive optimal approach hints
The pattern-retention problem
You forget 80% within a week
The DSA patterns you drill fade fast. We resurface each one at the right moment, just before you'd forget it.
Learn the scienceSee exactly where you stand.
Every session becomes one readiness score, your weakest patterns, and the next move for your practice.
Interview readiness
One score, calibrated to real FAANG rubrics, updated after every session.
Pattern mastery
Bar = you · tick = FAANG average
Progress
Week-over-week, so real gains stand out from a one-session spike.
Adapts to you
Detects whether you stall on setup, edge cases, or explaining, then targets it.
