Preparing for a software engineering interview can be challenging.
You can spend hours reading documentation, watching tutorials, and building projects. But when an interviewer asks you to explain JavaScript closures, React rendering, TypeScript generics, or frontend architecture, you might realize that understanding a concept and answering a technical question about it are two different things.
I wanted to build something that makes practicing these questions easier.
That's how DevTire started.

What is DevTire?
DevTire is a platform for practicing software engineering interview questions through multiple-choice quizzes.
The idea is straightforward: give developers a place to test their technical knowledge, practice important concepts, and prepare for technical interviews in a more interactive way.
Instead of simply reading about a topic, you can challenge yourself with questions and discover which areas deserve more attention.
Why I decided to build it
Technical interview preparation often involves switching between different resources.
You might use one website for JavaScript questions, another for React concepts, documentation for TypeScript, and a collection of articles for frontend system design.
These resources are valuable, but I wanted to bring different frontend interview topics together in one place.
I also wanted the platform to cover more than just basic programming questions.
Frontend engineering involves much more than writing components. Developers need to understand browser behavior, asynchronous JavaScript, state management, rendering performance, architectural decisions, and the trade-offs behind different approaches.
These are the kinds of topics I want DevTire to help developers practice.
What's available today?
The current version focuses on frontend development, with questions organized into dedicated topic categories.
Here are some of the areas covered:
- HTML & CSS: Semantic HTML, layouts, responsive design, and accessibility.
- JavaScript: Closures, promises, the event loop, runtime behavior, and core language concepts.
- TypeScript: Type systems, generics, utility types, and type-safe patterns.
- React: Components, hooks, rendering, effects, and performance.
- State Management: Context, Redux, Zustand, and shared-state strategies.
- Next.js: App Router, server-side rendering, caching, and routing.
- Design Patterns: Component composition and maintainable frontend architecture.
- Frontend System Design: Scalability, performance, architecture, and technical trade-offs.
The goal is to make it easier to practice individual subjects instead of treating frontend development as one enormous topic.
Practice at different experience levels
Developers don't all need the same level of preparation.
Someone preparing for their first frontend role has different needs from an experienced engineer interviewing for a senior position.
That's why DevTire organizes questions around three experience levels:
- Junior: Build a strong understanding of fundamentals.
- Mid-level: Develop deeper technical knowledge and understand practical trade-offs.
- Senior: Practice advanced concepts, architecture, performance, and engineering decisions.
My goal is to make the platform useful throughout a developer's learning journey, from strengthening the basics to preparing for more challenging technical interviews.
This is just the beginning
DevTire is still a work in progress.
Right now, the focus is on frontend development. I'm gradually expanding the question collection and improving the platform.
There are plenty of topics I'd like to explore as the project grows, including other areas of software engineering beyond frontend development.
I also want to keep improving the experience based on how developers actually use the platform.
Building a useful product isn't just about adding more features. It's also about understanding what users need, making the experience intuitive, and continuously improving the quality of the content.
Try it and share your feedback
If you're a frontend developer, preparing for a technical interview, or simply looking to test your knowledge, I'd love for you to give DevTire a try.
👉 Visit DevTire: https://devtire.vercel.app/
Try a few questions and let me know what you think.
I'm particularly interested in hearing:
- Which frontend topics would you like to see expanded?
- What makes a technical interview practice platform genuinely useful?
- Which software engineering topics should I add next?
Feedback and suggestions are welcome. They can help me decide what to build next and make DevTire more useful for the developer community.
Thanks for checking it out!
Let's make technical interview preparation more practical, one question at a time.
