Sample C# solutions to form a basis of code interviews
This solution is designed to test very basic knowledge of C#, it does use unit tests using nunit but the candidate need not really know about unit testing or nunit to do this.
There is an integration test that forms the basis of the testing which can test the end to end solution. Its up to the interviewer on how the interview progresess, should the candidate drive the code through pure TDD or just go and see what happens? either way there is an over arching test that can be used to guide the candidate to a correct solution.
