# Skill Challenges

This repo is where we store challenges to assess skills. These are mainly used in selection processes or the assessment of colleague skills internally.

## How to use

Make a folder for your challenge and store all related documents and artifacts there. Some ideas:

- You should, at minimum, provide `README.md` that provides details on the challenge.
- Additional contents like solutions, interview guides or candidate instructions, etc. are welcome as well.
