A comprehensive platform built specifically for frontend engineering interviews — from daily drills to full mock onsites.
Write real React, JS, and TypeScript in a Monaco editor with IntelliSense. Machine coding rounds run in Sandpack with a live preview — build components and see them render in real time.
Not a static grader. The AI acts as a real interviewer — asking follow-up questions, probing trade-offs, giving hints when you're stuck, and adapting difficulty to your level.
Design frontend architectures on an Excalidraw whiteboard. Draw component trees, data flows, and state management strategies under real constraints — just like a senior-round onsite.
Every session generates a detailed report: competency scores, evidence from your session, code quality analysis, communication feedback, and a prioritized improvement plan.
Question style, difficulty, and evaluation criteria are calibrated per company. Google SD rounds differ from Flipkart MC — we prep you for the interview you'll actually face.
Track topic-level performance, round-type stats, and company readiness scores. Activity heatmaps and streaks keep you accountable through your prep cycle.
DSA algorithms, machine coding with live preview, system design whiteboard, JS/React theory, and behavioral/hiring manager rounds — every format you'll encounter.
Summary, basic rubric, or deep coaching — evaluation depth scales with your credits. Deep mode cites specific moments from your session with evidence-based feedback.
Every session generates evidence-based feedback with rubric scores, specific citations, and a prioritized improvement plan.
Strong problem decomposition. Consider discussing time complexity earlier. Edge case handling for empty arrays was missed.
Every competency scored against real interview rubrics with numeric scores and evidence.
Reports cite specific moments from your session — not generic advice, your actual performance.
365-day activity heatmap, daily streaks, and longest-streak tracking.
Per-topic performance stats, round-type breakdowns, and company readiness scores.
Real prep paths. Deliberate practice, clear feedback, and better interview communication under pressure.

The simulator exposed exactly where my answers were weak. I stopped over-explaining and started giving structured, confident responses.

Practicing with rubric-based scoring made my prep measurable. The final onsite felt like a familiar flow instead of a surprise.

Cleared 2 onsite loops back-to-back
I had reusable frameworks for both technical and behavioral rounds. That gave me consistency across every interview panel.
