8Hey Fazier community! 👋 I'm the maker of PrepLoop — an AI-powered interview prep platform I built because I personally struggled to find one place that covered everything: mock interviews, DSA practice, aptitude, SQL, and company-specific questions. The idea started when I was preparing for tech interviews myself. I kept jumping between LeetCode, YouTube, random aptitude sites, and scattered resources. So I decided to build the all-in-one solution I wished existed. PrepLoop features AI mock interviews with voice feedback (powered by ElevenLabs + Deepgram), a visual DSA step-by-step animator, SQL practice, aptitude modules, and curated company-wise question banks. Would love your honest feedback — what would YOU want in an interview prep tool? Drop a comment, I read every single one. 🙏
The biggest challenge with interview prep is the "tab fatigue" from jumping between LeetCode, YouTube, and SQL editors. PrepLoop solves this perfectly. The AI mock interviews with real-time voice feedback are a game-changer for building confidence, and the DSA visualizer makes complex algorithms actually stick. It’s a must-have for any dev targeting top-tier tech roles.
PrepLoop is a game-changer for tech interviews! The AI voice mocks and the DSA visualizer make practicing incredibly effective. Highly recommended!
The combination of AI mock interviews with voice feedback and a DSA visualizer feels especially useful because it tackles both communication practice and problem-solving practice in one flow. I’d be curious to see benchmarks or examples of the feedback candidates receive after a mock session.
Keep full control of your data. Deploy Core free with Docker or Helm, or choose Enterprise for OIDC, SAML, SLAs, and dedicated support.
Strong idea with high potential, especially the AI mock interviews and DSA visualizer, which could differentiate it if executed well. However, it risks trying to do too much covering everything from coding to aptitude to SQL putting it in direct competition with platforms like LeetCode and HackerRank. The key will be focusing on a clear core strength (like AI feedback or visualization) and delivering genuinely high-quality, personalized insights rather than spreading too thin.
Strong angle. The interview-prep space gets crowded fast, so the fastest credibility win here is showing before-and-after improvement: mock interview score change, time-to-offer, or confidence lift after a session. If you can surface one sample feedback report in the landing flow, the value will be easier to trust.
