Questions & Answers

As answered by people managing Tomodachi Prep and Project Euler.

What makes your product unique?

Tomodachi Prep's answer

Tomodachi Prep is the only platform that combines real peer-to-peer mock interviews with AI-powered practice in a single, gamified experience. Instead of practicing alone or paying expensive coaches, users get matched with real peers for live coding interviews, complete with a collaborative code editor, real-time feedback, and a gem-based reward system that keeps them coming back. It's interview prep that feels like a game, not a chore.

Why should a person choose your product over its competitors?

Tomodachi Prep's answer

Most interview prep platforms offer either pre-recorded content or expensive 1-on-1 coaching. Tomodachi Prep gives you unlimited live practice with real people, the closest thing to a real interview, at a fraction of the cost. Our smart matching pairs you with peers at your level, our AI interviewer is available 24/7 for on-demand practice, and our gamification system (gems, badges, leaderboards) makes consistent practice feel rewarding. You don't just study, you build the muscle memory that comes from doing.

How would you describe the primary audience of your product?

Tomodachi Prep's answer

Software engineers and computer science students preparing for technical interviews at top tech companies. Whether you're a new grad targeting your first role, a mid-career engineer eyeing FAANG, or a career switcher breaking into tech, if you need to ace a coding interview, Tomodachi Prep is built for you.

What's the story behind your product?

Tomodachi Prep's answer

"Tomodachi" means "friend" in Japanese. The idea was born from a simple truth: the best way to prepare for interviews is to practice with others. But finding reliable practice partners is hard. Study groups fall apart, schedules don't align, and feedback is inconsistent. Tomodachi Prep solves this by creating a global community where anyone can find a practice partner instantly, get structured feedback, and track their progress, turning interview prep from a lonely grind into a social, motivating experience.

Which are the primary technologies used for building your product?

Tomodachi Prep's answer

Tomodachi Prep is built on a modern, enterprise-grade cloud stack designed for reliability and real-time collaboration. The platform features a robust backend API, a responsive single-page web application, a dedicated real-time collaboration server for live coding sessions, and an AI voice agent that conducts realistic mock interviews using state-of-the-art speech and language models, all hosted on AWS infrastructure.

Who are some of the biggest customers of your product?

Tomodachi Prep's answer

  • Software engineers preparing for interviews at Google, Amazon, Meta, Apple, and Microsoft
  • Computer science students at top universities gearing up for internship and new-grad recruiting cycles
  • Coding bootcamp graduates building confidence before their first technical interviews
  • Career switchers from non-tech backgrounds breaking into software engineering roles
  • Engineering teams at startups using the platform for internal skill-building and hiring practice
