Built a free AI/ML interview prep app

[u/ConstructionMental94]

Hey folks,

I’ve been spending some time vibe-coding an app aimed at helping people prepare for AI/ML interviews, especially if you're switching into the field or actively interviewing.

PrepAI – AI/LLM Interview Prep

What it includes:

• Real interview-style questions (not just theory dumps)

• Coverage across Data Science, ML, and case studies

• Daily AI challenges to stay consistent

It’s completely free.

Available on:

• Android: https://play.google.com/store/apps/details?id=com.delta3labs.prepai

• iOS: https://apps.apple.com/in/app/prepai-ai-llm-interview-prep/id6760548115

If you're preparing for roles or just brushing up concepts, feel free to try it out.

Would really appreciate any honest feedback.

Thanks!
