Go Interview Challenge

Template interview challenge for the GPS Insight api team

This repo contains a little demo service for pulling data about intraday stock values off of a kafka stream and inserting them into a postgres database. The service also has a rest api for making that data consumable by clients.

What is the point of this challenge?

  • Demonstrate an ability to quickly get comfortable in a new codebase and make contributions
  • Demonstrate familiarity with the technologies we use every day
  • Show us your approach to solving problems

Prerequisites

What will you be implementing?

  • Consume kafka stream and write to postgres database
  • Implement REST endpoint to get stock info from the database
