“Frontend Monsters has really helped prepare me for many of my frontend internship interviews - their front end system design guidebook is stellar and it helped boost my confidence to write front end components faster during time paced interviews. Thank you, FM!”
“This was the first time I gave full stack / frontend interviews. Coming from Meta, working in frontend for 3 years, I still felt that I had a lot of loopholes in basics of JavaScript, HTML. The question bank of FM covers almost everything that might ever be asked in frontend interviews for companies including startups and FAANG. Thanks to the amazing question bank and conversational language in the explanations, I was able to crack a senior role at Snap.”
“Frontend Monsters was a game-changer for my interview prep. The real-world coding challenges and detailed solutions helped me understand not just the "how" but the "why" behind each problem. The platform's UI made it easy to focus and track my progress. I landed my dream job at Google, and I credit a big part of my success to FM!”
