Welcome to your interview.
The question is on your right: Live-Coding C# Application Design. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
During a technical interview, you were asked to solve a C# challenge involving modeling and implementing an application through live coding while explaining your design decisions and reasoning.
