Hi everyone 👋 I'm Abhijeet - the solo developer behind Stack Interview.
I built this because I kept running into the same three problems every time I was preparing for interviews:
→ Good questions for my exact stack were scattered across dozens of old blog posts
→ DSA practice meant switching to a different platform and setting up a local environment
→ I had no way to know if I could actually explain my answers clearly until I was on the real call
So I built one place that does all three.
🧠 1,000+ interview questions - React, Node.js, Next.js, TypeScript, MongoDB, SQL, System Design and more. Scenario-driven, senior-level - not definitions.
💻 215+ DSA problems - live code execution right in the browser, AI hints on demand, a weakness radar, and a company readiness score.
🎤 AI Mock Interviews - answer by voice, get scored per answer on technical depth, communication, and confidence. Pick a company and the AI tailors every question to their style.
Everything is free. No paywall on any content. No forced sign-up.
I'd love to hear from you:
• Which of the three would you reach for first when prepping?
• What tech stack or company question set is missing that you actually needed?
Ask me anything - happy to talk product, tech, or what's coming next 🙏
