The Business Context

Developers preparing for technical interviews are stuck stitching together prep from scattered sources: LeetCode for DSA, blog posts for system design, YouTube for framework-specific questions. We wanted to build a single, focused destination that covers the full interview funnel without the noise.

The Challenge

Most existing prep tools either lean too heavily into raw problem-grinding without context, or bury useful answers behind paywalls and account walls. The goal was a fast, mobile-first, completely free resource that respects a candidate’s limited prep time.

Our Approach & Solution

  • Structured Question Library: Built a library of 2,500+ questions across 30+ topics spanning React, JavaScript, System Design, DSA, and Backend Engineering, each with a TL;DR summary plus a full explanation.
  • Difficulty-Aware Filtering: Implemented chip-based filters and full-text search so candidates can laser-focus on Easy, Medium, or Hard questions by topic instead of scrolling endlessly.
  • Zero-Friction Access: No account, login, or paywall. The entire library is accessible immediately, prioritizing speed of access over lead capture.

The Results

  • 2,500+ Questions Live: Spanning frontend, backend, mobile, and system design topics at launch.
  • Mobile-First Design: Fully responsive accordion-style layout built for quick review sessions on any device.
  • Continuously Updated: New questions added weekly, with the full question bank audited monthly to stay current.
