Interview prep
that actually
prepares you.

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.”

How it works

Three steps to being
genuinely ready.

01

Pick your interview format

Choose from Product Design, Behavioral, Coding, Strategy, and more. Filter by PM or SWE track. New formats ship regularly.

02

Work through the framework

Enter your question. PrepHub walks you through a structured coaching process — clarifying questions, user analysis, solution framing, risk identification, metrics.

03

Walk out prepared

You've practiced the thinking process, not a script. That's exactly what interviewers test for, and it's what PrepHub builds.

Why PrepHub

Built for how
interviews actually work.

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.

Framework-first, not answer-first

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.

Stakeholder-aware behavioral coaching

Behavioral prep that adapts to who's asking. Engineers probe for collaboration differently than executives probe for leadership. Your STAR answer should reflect that.

Bring your own API key

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.

PM and SWE in one place

Product sense, behavioral, coding, system design — one tool for every interview format you'll encounter, regardless of which track you're interviewing for.
