NetRom Software C# Developer interview questions

The interview was available for two days. In the first day and at least half of the second day you need to implement a small application from scratch using one of the .net technologies, windows forms for me at that time. In this time, a person is coming to you and putting different questions about oop, databases, different projects from faculty or about your current experience. At the end of the application, another person is introducing a bug in your app, and you have to use the debugger to identify it. In the second part of the second day you also have to resolve different code problems (you have a matrix with 0 and 1, count the number of zones of adjacent 1 values).
