At my internship we as interns had to work on a CRM system. We used the google api since the company is using google accounts already. Before the project is done my internship is over but I could start my traineeship 4 weeks later.

Together with another old intern/now trainee I spent 4 hours on debugging the login system the first day we came back. Turns out somebody thought we didnt need the application keys anymore and thus deleted the application from the google developer console....
