# Code Problem Reference Implementations

The purpose of this repository is to house a set of reference
implementations for the coding exercises and problems we use in our 
engineering candidate interviews. Interviewers should look through
the references for the problems they intend to use so they're familiar
with what we're looking for.

The problem bank for code exercises can be [found here](https://drive.google.com/drive/folders/1_XZk4ppwORAYbEhwFfcMPhPDd200uwnf)
