devtools.tech has been super helpful in my prep for product-based company interviews. It’s rare to find a platform that brings all types of quality problems together in one place. The question variety and structure really stand out. It saved me a lot of time and gave me the exact kind of practice I was looking for.

devtools.tech was a huge help in my frontend interview preparation. The content is super focused and practical—it kept me on track and made a real difference. Thanks to it, I ended up landing 4 offers in the frontend field. Highly recommend it to anyone prepping for frontend roles.

I was skeptical about paying for interview prep when so many free resources exist, but devtools.tech proved its worth immediately. I like that questions are tagged by companies so I know what to prepare and focus on if an interview is coming up. The best part is, a lot of questions were asked as it is in many companies! I also liked the frontend system design guide. It was well structured and helped me develop a framework for approaching system design interviews. I would recommend devtools.tech to anyone looking to prepare for frontend interviews.

There aren't many good resources for frontend interviews. A lot of platforms focus on Leetcode-style questions but don't cover the topics that are actually asked in frontend interviews. I found devtools.tech to be different, the questions are well categorized and the solutions are very helpful. I was asked Promise polyfill question in an recent interview and I was able to answer it because I solved it on devtools.tech platform. Their system had 18 test cases for this question which helped me cover all the possible cases. It was instrumental in my interview preparation journey!

devtools.tools helped me crack 3 great offers! The platform offers a wide variety of questions — from the basics that help you brush up on fundamentals to the ones commonly asked in top tech interviews. Since it's frontend-focused, it really simplifies the experience for candidates. The UI is easy to navigate, and the in-browser editors require almost no learning curve — you're ready to code right away. What stood out the most were some truly unique questions I couldn’t find on any other platform. The company tagged questions and video tutorials are also super handy, especially when you're juggling multiple interviews. Highly recommend it to any frontend dev prepping for the job hunt — or anyone who just wants to keep their coding hands sharp!

devtools.tech has helped me a lot. The questions are very rich and need a lot of thought to come up with possible solutions. This is by far one of the best resources to prepare for FE interviews. I still feel this is not getting the attention it deserves and is very underrated at the moment.

devtools.tech has been a game-changer in my journey as a frontend engineer. The content is top-notch—well-structured, deeply practical, and covers everything from JavaScript and TypeScript to React and frontend system design. It helped me go beyond just writing code to actually understanding how things work under the hood. What I love most is how consistently they update the platform with fresh, relevant content that pushes you to level up—whether you're a beginner, intermediate, or aiming for mastery.

If you're preparing for frontend roles, I can't recommend anything better than devtools.tech. I always thought I was prepared until I started solving questions on the platform and realized how much I was missing and the levels of gap in my understanding. It didn't just help me with interviews, it genuinely levelled up my frontend knowledge. What really brought it all together was their YouTube channel, the way complex frontend concepts were explained with such clarity and depth is something you don't come across often. I constantly switched between the diverse platform and the videos, learning and applying in real time. Thanks to this combo, I was able to crack interviews at both PayU and Apollo.io. devtools.tech was truly a game-changer in my interview prep journey.

I find frontend interviews tough. There's no clear, affordable guide for system design discussions, and with so many people switching jobs for better pay and work culture, it feels like everyone else caught up—except me. I'm trying to sharpen my skills in UI refactoring, JavaScript tricks, and understanding how features and tools work under the hood. Writing a polyfill isn’t just about impressing interviewers—it helps me stay sharp. When I build components in vanilla JS, I focus not just on making them look good, but also on using browser resources efficiently. I train on devtools.tech the same way an athlete trains on the field.

devtools.tech has been an invaluable part of my interview preparation. The platform offers a vast range of thoughtfully curated questions across different difficulty levels, which helped me build confidence and improve my problem-solving approach. I especially appreciated the real-world scenarios and practical coding exercises—they closely mimic what’s asked in actual interviews. The consistency and variety devtools.tech provides kept me engaged and motivated throughout my prep. I’d highly recommend it to anyone looking to strengthen their technical skills and crack interviews at top tech companies.

devtools.tech has been incredibly helpful throughout my frontend journey. It’s a well-organized platform that brings everything you need for interview prep into one place like questions, video tutorials, collections, company guides, and resources to grow as a developer. What I really appreciate is the range of topics it covers from machine coding and UI-based challenges to quizzes and frontend system design. The platform even helps you understand how different companies structure their interviews, which makes targeted preparation much easier. One of my favorite features is the “Try a Random Question” option, perfect for days when you’re unsure where to start. I really like the video tutorials, they’re detailed and easy to follow. Yomesh breaks down each concept clearly and explains how to approach problems step by step, which is really helpful for interviews. Thank you Yomesh, for creating such a fantastic platform! 😊
