THE PROBLEM
You’re learning. But is it adding up?
- Reading documentation helps.
- Watching tutorials helps.
- Building projects matters.
Your preparation is spread across docs, videos and side projects. So it’s hard to know:
- ?What you have already covered
- ?What you still need to practice
- ?Which concepts you are weak in
- ?Whether you are actually improving
- ?Whether you are ready for the interview
HOW YOU PRACTICE
Learn what you don’t know. Practice what you think you do.
Technical interview preparation should be more than memorizing answers. NerdBeing helps you understand a concept, then test whether you can actually use that knowledge.
THE QUESTIONS
Questions that make you think, not just recall.
Every question asks you to use what you know, the way an interviewer would.
Predict what code will do
Identify a bug
Compare two approaches
Reason about performance
Design a system
Debug a production scenario
Explain engineering trade-offs
TRACKS
Practice for the interview you’re actually facing.
Practice backend interview questions
Backend interviews often go beyond writing APIs. NerdBeing helps you practice those concepts before the interview, including Go.
- Goroutines
- Channels
- Context
- Interfaces
- Databases
- Caching
- Networking
- Queues
- Distributed systems
- Debugging
- Performance
Practice frontend interview questions
Frontend interviews are also more than writing components. Practice the decisions interviewers actually ask about, including React.
- Rendering
- State
- Hooks
- Lifecycle
- Memoization
- Browser behavior
- Component design
- Performance
- Architecture
Practice system design before the real discussion
There is rarely one perfect answer. Practice reasoning about trade-offs, scale, and the decisions you would explain out loud.
- Scalability
- Load balancing
- Caching
- Databases
- Messaging
- Microservices
- API architecture
- Reliability
- Availability
- Trade-offs
YOUR PROGRESS
Saying it is easy. Interviews check if it’s true.
“I know Go.”
“I’ve worked with React.”
“I understand system design.”
NerdBeing shows you what you really know:
- 01Practice across topics
- 02See where you perform well
- 03Identify where you struggle
- 04Revisit weak areas
FITS YOUR DAY

WHY WE BUILT IT
“Every interview wanted a different engineer. My preparation was scattered across a hundred tabs. So I’m building the app I needed.”
Hitesh, building NerdBeing
- Preparation, not certification.
- Understanding, not memorising answers.
- A clear path, not a hundred tabs.

About NerdBeing
NerdBeing is a technical interview preparation platform for software engineers. It helps developers practice engineering concepts, test their knowledge, identify weak areas, learn from explanations, and prepare before real technical interviews.
Interview preparation is the main goal. But strong interview preparation comes from understanding engineering concepts properly. NerdBeing helps you practice those concepts, identify what you do not understand, and improve before you face the real interview.
No. NerdBeing covers broader software engineering knowledge such as programming languages, backend engineering, frontend engineering, databases, APIs, concurrency, software design, system design, architecture, performance, debugging, and production concepts.
NerdBeing and LeetCode focus on different areas of preparation. LeetCode is primarily known for coding and algorithm problems. NerdBeing focuses on broader software engineering interview preparation, including technical concepts, architecture, system design, practical scenarios, and engineering reasoning.
Who it’s for
Yes. Backend engineers can practice topics such as Go, APIs, databases, concurrency, distributed systems, caching, queues, messaging, system design, performance, and backend architecture.
Yes. Frontend engineers can practice topics such as React, rendering, hooks, state management, component architecture, performance, and frontend engineering concepts.
Yes. NerdBeing is designed to support preparation beyond beginner-level questions. Experienced engineers can practice architecture, concurrency, distributed systems, production debugging, performance, system design, design trade-offs, and advanced engineering concepts.
How it works
NerdBeing gives software engineers structured technical practice instead of random interview questions. You can practice by subject and topic, answer questions, use hints, review explanations, identify weak areas, and continue practicing until your understanding improves.
Yes. The goal is not only to show whether an answer is right or wrong. NerdBeing is designed to help you understand why the answer is correct, why the alternatives may be wrong, and what concept you need to improve.
You are more prepared when you can consistently recall, explain, reason about, and apply engineering concepts without relying on memorized answers. NerdBeing helps you assess this through repeated practice, topic-based questions, explanations, progress tracking, and weak-area identification.
Walk into the interview knowing what you know.
