Launching Prepin - AI Mock Interview Platform

Hey Indie Hackers! I'm excited to share Prepin, a project born from a simple observation: being great at your job doesn't automatically make you great at interviews.

💡 The Problem I noticed many talented professionals missing out on dream opportunities not because they lacked skills, but because they weren't prepared for the interview itself. Traditional mock interviews with friends or recording yourself just don't cut it - they lack real feedback and the pressure of a real conversation.

🛠 The Solution Prepin is an AI-powered mock interview platform that:

• Conducts realistic video interviews

• Provides instant, actionable feedback

• Adapts questions to your industry and experience

• Tracks your progress over time

• Lets you practice unlimited times

🎯 Current Status

• Growing user base in tech, finance, and consulting

🔍 Tech Stack:

• GPT-4 API

• WebRTC for video

• Custom emotion analysis

💭 Next Steps We're focusing on:

• Expanding industry-specific question banks

• Enhancing feedback algorithms

• Building interview preparation roadmaps

• Adding collaborative features

Would love to hear your thoughts and feedback! Has anyone else tackled the interview preparation space? What challenges did you face?
