AI coaching built on real interview frameworks. Not scripted answers to memorize — structured guidance that trains how you think.
“I stopped memorizing answers and started thinking like interviewers expect — and landed the offer.”
Priya Sharma · PM, GoogleHow it works
Choose from Product Design, Behavioral, Coding, Strategy, and more. Filter by PM or SWE track. New formats ship regularly.
Enter your question. PrepHub walks you through a structured coaching process — clarifying questions, user analysis, solution framing, risk identification, metrics.
You've practiced the thinking process, not a script. That's exactly what interviewers test for, and it's what PrepHub builds.

3 creditsWhy PrepHub
Most prep tools give you sample answers to memorize. PrepHub gives you the frameworks behind great answers — so the thinking becomes second nature, not something you perform.
We don't generate scripted answers. PrepHub surfaces the mental models and decision frameworks that interviewers are trained to look for — so you can handle any variation.
Behavioral prep that adapts to who's asking. Engineers probe for collaboration differently than executives probe for leadership. Your STAR answer should reflect that.
Use your own Gemini, Groq, or OpenAI keys. We encrypt them at rest with AES-256-GCM. We never see your key in plaintext, and you control your own usage costs.
Product sense, behavioral, coding, system design — one tool for every interview format you'll encounter, regardless of which track you're interviewing for.
