Drop a problem. Watch it get solved.
Paste a DSA problem, or attach a screenshot. The agent analyses the constraints, writes Python, actually runs it against sample and adversarial edge cases, fixes failures, and only then answers. Built for timed online assessments.
Walk into the interview ready.
Paste (or dictate) the problem. You get the full playbook: problem understanding & clarifying questions, brute force, the optimal approach with a worked example and diagrams, commented runnable code (actually executed), a line-by-line walkthrough, complexity, edge cases — and 💬 exactly what to say out loud.
Coding Interview — structured, in your language.
Experimental. Same full walkthrough — understanding, pattern, brute-to-optimal bridge, verified code, complexity, edge cases, follow-ups — but every section arrives as a typed, colored card. Pick Python or Java in the top bar and the whole solution generates in that language.
Low Level Design — structured, in your language.
Experimental. The full LLD interview — candidate-led scoping, entity accept/reject, class cards, diagram, algorithms, verified code walkthrough, concurrency — every section as a typed, colored card. Pick Python or Java in the top bar and the whole design codes itself in that language.
Low Level Design, explained as you'd say it.
Give an OOD problem. You get the full playbook: requirements, core objects, a class diagram, design patterns & SOLID, then the code narrated class by class (not dumped), actually run to prove it works, a sequence diagram, concurrency & edge cases — with 💬 exactly what to say.
System Design, end to end.
Give a system-design problem. You get requirements (functional + non-functional), capacity estimates, API & data model, a high-level architecture diagram, deep dives, scaling, trade-offs and failure modes — researched with live web search where it helps, and 💬 exactly what to say.
System Design — structured, not just Markdown.
Same full HLD walkthrough — requirements, capacity, API & data model, architecture diagram, deep dives, trade-offs — but the model emits typed, structured sections instead of Markdown. Guaranteed colors and layout per section, and diagrams that can't break from stray formatting. Experimental.
Behavioral & hiring-manager rounds — in your own voice.
Ask any behavioral, cultural-fit, or resume question — or just say "tell me about yourself". The coach answers in your voice, grounded in your real projects and stories, in tight STAR form, with the deep-dive defense and 💬 exactly what to say. Name the company (Amazon, Google, a startup) and it re-tilts. Read it aloud to practise saying it.
