The first stage was a take Home project where you have to Refactor an existing .NET console app. Apply SOLID and DDD to refactor the classes to make it more readable, testable, configurable and extensible. Fix any bugs or code smells that you see. They didn't care about the implementation. They said it should take no more then 2 hours - it took me 3 hours The task description was very vague on details. Because of the lack of clarity, it made it harder to structure the code and the project files. It seemed like they had some way to test the project with some input but they did not provide that to you, instead they hard coded values in the entry class. The project given was a very unrealistic, in the sense it required a lot of work to be production ready. The 2 hours they suggest would barley cover going through the project, understanding what it does and then refactoring it. This is not factoring writing tests. After all that, they did not provide any feedback.
