Knowing the answer isn't the same as explaining it under pressure. Most interviews aren't lost on knowledge, they're lost in the ramble. devprep.app: AI interview practice for developers. Try it free. #CodingInterview #buildinpublic

New feature coming to DevPrep: whiteboard-style coding challenges. Write real code, get scored on correctness and complexity, not just voice interviews and flashcards anymore. What's your experience of whiteboard interviews actually been like? #CodingInterview #buildinpublic

I built devprep.app to help devs practice interviews out loud instead of just reading LeetCode answers. because knowing the answer and being able to say it under pressure are two different skills. What's the worst part of interview prep for you? #buildinpublic #TechInterview

I used to freeze in technical interviews. Not because I didn't know the answer, because I'd never actually said it out loud before. Knowing something and being able to explain it clearly under pressure are two different skills. That's the whole reason DevPrep.app exists. devprep.app #TechInterview #100DaysOfCode

Added this new feature: a "Download cheat sheet" button on DevPrep.app. It looks at your actual weak interview answers and generates a PDF of the corrected key facts, so you're not googling generic prep material the night before. devprep.app #buildinpublic #TechInterview

I built DevPrep.app because I kept knowing the answer but falling apart when someone asked me out loud. This is what a practice session looks like. The AI asks a real question, listens to your answer, and pushes back just like a real interviewer would. Free to try. devprep.app
