LowkeyPrepped 🚀

LowkeyPrepped redefines interview preparation with an AI-powered mock interview platform designed specifically for software engineers. It’s not just another practice tool; it’s a personalized coaching experience that delivers realistic mock interviews covering both technical and behavioral aspects.

Our conversational AI simulates real-world interview scenarios, providing:

• 💬 Instant feedback on responses
• 🎯 Highlighting areas for improvement
• 🤖 Guidance when a user gets stuck

Technical interviews are challenging, but LowkeyPrepped breaks them down, helping users tackle everything from coding questions to system design.
