The first recruiter interview was very basic questions about your background and why you were interested. The interview with the director of engineering was a little more focused with still the basic standard interview questions like "what is your proudest career moment", and a few more questions directly related to the job. The technical interviewer, since I was interviewing for a C# position, was looking for very specific answers to his questions. First, he asked the difference between abstract classes and interfaces, then the difference between reference and value, then what static classes vs. singleton classes were. Then he wanted me to describe the MVVM framework, and he wanted to know what interface that classes should inherit to avoid hash collisions when using objects as Dictionary keys. He asked about data triggers, data binding, He asked what ascynchronous methods do; he wanted to know about the Dispatcher class. He gave me a snippet of code, something like Task.Delay(1000).CompleteAsync and asked me to explain what it did.
