Answers built from your real experience
Most engineers use Prepto for high-stakes roles
Built for mid & senior engineers
"I've designed and shipped complex systems. I can talk about distributed architecture for hours. But when an interviewer asks me to walk through a critical technical decision from my experience, I still catch myself rambling or missing key points. Most prep focuses on abstract questions and ignores the hard part — turning real work into clear, structured interview answers."
— Creator, Prepto

How Prepto Prepares You

From a job posting and your resume to a complete interview playbook — built automatically.

Capture the Role

Save a job with the Chrome extension from any job board, or paste the description into Prepto. Every opportunity gets its own workspace.

Mira Studies You & the Role

Mira (your agent) analyzes the job description, your resume and tech stack, infers what they're really testing for, and generates 40–80 role-specific questions.

3

Answers Built From Your Work

You get detailed answers and talking points grounded in your own projects — with trade-offs, architecture choices, and failure stories you can use in the interview.

4

Track Progress & Interviews

Mark topics as covered, log what was actually asked, and track every stage of each application so your next interview is even sharper.

"How did you break down your monolith into payment microservices? What trade-offs did you make around consistency, latency, and failure isolation — and what would you do differently now?"

Not Just One Interview. Your Whole Hiring Loop.

Today, Prepto prepares you for a specific role. It's steadily becoming a system for managing your entire job search.

Before

Organize High-Stakes Roles

Save roles from any job board, keep descriptions, links, and notes in one place. See which interviews are coming up and where each opportunity sits in your pipeline. Most engineers use Prepto for the roles they care about most.

During

Stage-Specific Preparation

Screenings, deep technical rounds, architecture interviews — each demands a different angle. Use Prepto as your interview workspace with questions, answers, and your notes side by side.

After

Log What Actually Happened

Record what they asked, how you answered, and where you stumbled. Over time, see patterns across companies and roles instead of treating each interview as a one-off. Deeper analytics and Gmail/Calendar integrations are in active development.

Why This Works Better Than Generic Prep

Not "grind random questions and hope". Actual preparation for the roles you're targeting now.

Grounded in Your Real Work

Prepto doesn't invent generic stories. It looks at what you've actually built and turns your decisions, trade-offs, failures, and wins into interview answers you can own.

Role-Specific, Not Random

Interviewing for a React role? You'll prep component patterns, performance, and data flow — not JVM internals. Senior backend? Expect architecture, scalability, and reliability questions, not just syntax trivia.

Helps You Think & Speak Like a Senior

It's not about memorizing scripts. Prepto shows you how to frame your work with context, constraints, options considered, and trade-offs — the way strong senior and staff engineers do.

Your Interview Workspace

A focused place where your roles, questions, answers, and interview history live together.
