Overview

This exercise is meant to showcase your technical abilities by conducting a code review on a Pull Request (PR).

• You will be given links to the PR, as well as the issue trying to be solved, a day before your scheduled interview so you have context of the change and an opportunity to inspect the code ahead of time.
• You will pair with a Gaggle software engineer to walkthrough the assigned PR together.
• There will be a number of things we are looking for, but this process is not meant to be stressful.
