Spiele-Palast interview questions

Interview process was quite common. First it was interview with Head of Studio, where introduced me company, told, what they were doing and after asked me couple of quetions like why I want to work with company, what I find interesting and so on. After around a 5 days I've had an interview with Technical Director, where he asked me really common questions about Unity and C#: What is SOLID? Have I worked in 2D before? Do I have an experience with Dependency Injection Frameworks? To conclude I can say, that I liked company's honesty and they managed to answer all my questions without hesitation. However, I noticed that during the interviews everyone was talking a little sluggishly and as if without any desire to conduct this interview. At the technical interview, I felt like the interviewer ran out of questions at one point and we just chatted for a while.
