Free interview questions and detailed answers for Java, React, Node.js, Go, SQL, System Design, Kafka and Microservices. Track what you have read and solved.
The idea came from a problem I faced while preparing for technical interviews: the process was too scattered.
Interview questions were spread across browser bookmarks, PDFs, notes, YouTube videos, GitHub repositories, and different websites. I could read a question once, but it was difficult to remember:
- Which questions I had already covered
- Which concepts I understood well
- Which questions needed revision
- What I should study next
I wanted to build something more focused than a simple question bank.
The goal was to create one place where learners can explore interview questions by technology, difficulty, company, and progress—and manage their preparation in a practical way.
While building it, the project evolved from a basic Java and React question collection into a more complete interview-preparation platform. I added user authentication, progress tracking, solved and visited status, flagged questions for revision, a personal profile dashboard, search and filters, company-based question tracking, and an admin workflow for managing content.
One of the biggest learnings was understanding that the user experience matters as much as the question content. A platform can have hundreds of useful questions, but if users cannot quickly find, save, revisit, and track them, the learning process still feels overwhelming.
So I focused on making the journey simple:
1. Find a relevant question
2. Read and understand it
3. Mark it as visited or solved
4. Flag it if it needs revision
5. Return to the dashboard and continue from where you left off
The project is still evolving, and I’m continuing to improve it based on real user feedback.
I’d love to know: what part of interview preparation do you find the most difficult—finding good questions, staying consistent, revising, or tracking progress?
