Your Software Engineering Interview Toolkit
Handpicked Problems
We teach you the most important concepts in the fewest questions. We have taught this curriculum 3-times over and weave related concepts between topics effectively.
Full Coding Environment
We support the most popular programming languages so you can get hands-on experience implementing solutions to each problem. The best way to learn is by doing.
AI Teaching Assistant
Have a context-aware AI-assistant on standby to help you as you study. Your assistant will be aware of the problem, solutions, your workspace code, any active errors, and more. Ask it anything!
Optimal Solutions
We provide solutions to all problems we teach. We start with the brute force & incrementally reach an optimal solution. Solutions are translated into multiple languages.
