I was given credentials to clone a repo from Bitbucket that contained instructions to develop a simple contacts management app (basically a todo app with more than 1 text field). The spec required complete support for IE11 and Edge.
The given due date on the task was 3-5 hours after which the candidate is supposed to push the results back into the repo in a branch named after themself.
The README.md that contained the instructions was riddled with spelling mistakes.
They required to pull coordinates from the Google Geocoding API, but didn't provide me with a working API key. I kept the AJAX call but used a hardcoded value for the result as a compromise.
