Internship challenge has moved to https://github.com/techchapter/interns-challenge. This challenge is intended for applicatns for apprentenships only.
At Tech Chapter we receive a lot of applications for apprenticeship from allover the country. Allthough we are very excited about this, we have limited capacity in interviewing all applicants. Because of this we have decided to present all applicants with a coding challenge that will help os give a better insight in your current coding skills and to give all application similar conditions in our assessment.
There is not a single solution for this challenge, and it is not a recuirement to complete all task. The idea is to give us a better understanding of your coding skills while you will get a better understanding of our expectations for your first time as apprentice at Tech chapter.
The challege is created in the C#.NET coding language as this is widely used throughout the data technician education centres. If you prefer a different language please let us know at apprentice@techchapter.com
When you have finished challenge please archive and submit your solution to apprentice@techchapter.com along with your application, resume and any grade sheets you may have.
Happy coding ;-)
In this repository you will find three tasks:
- Mario's Pizza
- Input validation
- Holiday Calendar (difficult)
Common for all tasks you will find a number of Interface files within the src/-folder along with some stub Class implementations of the Interfaces. In the tests/-folder you will find some NUnit test cases defined for the class implementations. Since the classes are currently stubbed the test cases will fail. Your job will be to change the class implementation to make the unittest cases pass. Once the testcase passes, the task is completed in accordence with TDD principles.
Note: you should NOT do any changes to the Interface files or the test case files, but you may change or add any class implementation as you see fit.
Below you will find user stories for all tasks.

For the Tech Chapter timeregistration we need to notify employees if they forget to do their time registration. However, holidays are days off why they do not need to fill in their hours.
Hint: Holidays are a national mater not supported by the GregorianCalendar typically used for Calendar functionality within C#. Especially the easter can cause issues, since the days will vary from one year to the next based on the moon cycle. Also Maundy Thursday is a Holiday in Denmark but not in other countries like Sweden. Salling Group, that runs a large number of supermarkets has exposed an API of Danish holidays that may help you in succeeding this task. You will need to sign up for a token before you can start the integration.
