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.
π‘ 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.
π 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
π― Current Status
Launched beta version
500+ practice interviews conducted
4.8/5 average user rating
Growing user base in tech, finance, and consulting
π Tech Stack:
React + Vite
Node.js
GPT-4 API
WebRTC for video
Custom emotion analysis
π 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?
Congrats with launching!
Could you provide more details what exact data the Prepin is collecting from the user and how it generates the feedback?
Prepin is collecting only data that user uploaded , liek CV, coverletters and job descriptions.
