CapTrivia: Cap Table Trivia Game

Introduction

Welcome to CapTrivia, a cap table trivia game developed by Pulley. This project is part of our engineering interview process, designed to assess your coding skills and problem-solving abilities. Currently, CapTrivia is a simple, single-player game. Your challenge is to develop it into a multiplayer experience.

Project Overview

• Current State: CapTrivia is a functioning single-player game with basic features. We tried our best to make it very ugly so that you have lots of room to improve it!
• Tech Stack: The front end is built with React (in App.js), and the back end with Go (in main.go). We also included a docker-compose.yml so that you can easily run this locally (it includes a PostgreSQL instance).
• Objective: Transform CapTrivia into a multiplayer game where users can create games, invite others via a shareable link, and compete in real-time trivia challenges.

Quickstart

1. Make sure you have Docker installed. https://docs.docker.com/engine/install/
2. In the captrivia root directory, run docker compose up.
3. Open http://localhost:3000 in your browser to see the game.

Your Task

1. Refactor and Enhance: The current code is intentionally basic and contained in single files for both front and back ends. Your first task is to clean up and structure the codebase.
2. Implement Multiplayer Functionality:
   • Allow users to start a new game and generate a shareable link.
   • Enable real-time joining of players in a waiting room.
   • Implement a countdown and start the game simultaneously for all players.
   • Introduce a scoring system with a configurable number of questions (default: 10).
   • Players will compete to answer each question first. For each question, the player who answers first gets the points.
   • Display the winner at the end and allow users to start new games.

Time Allocation

You should aim to spend no more than 5 hours on this challenge. We respect your time and want to see what you can achieve within these constraints.

Submission Guidelines

• Git Patch: Submit your solution as a Git patch file(s). This allows us to easily review your changes against our original code. You can do this with git diff starting_commit..HEAD > captrivia.patch or git format-patch --root start_commit..HEAD (start_commit should be the commit before your first commit, it will not be included in the diff/patch).
• Running Locally: Please ensure that we can run your version with docker compose up.

Evaluation Criteria

• Code Quality: Clean, readable, and well-structured code.
• Problem Solving: Effective and efficient solutions to the challenges presented.
• Creativity: We appreciate innovative approaches and ideas.
• Tool Utilization: Feel free to use tools like GitHub Copilot and ChatGPT. We value efficiency and resourcefulness.

After Submission

Once we receive your solution, we'll schedule a live code pairing session. Here, you'll walk us through your code, and we'll collaboratively work on an additional small feature.

Conclusion

Thank you for participating in Pulley's engineering challenge. We're excited to see your approach to enhancing CapTrivia. Good luck, and have fun!
