Evertz Microsystems Software Engineer (DSP/Embedded Programmer) interview questions

I applied for the position and after a short HR phone interview I was invited for the technical part. Three guys with different background.... the first was an asian young software engineer who ask me some general question about my experiences and gave me some C++ questions on paper... The second, an Indian guy who did not speak a lot just shooting some algorithmic questions... The third one, who was a mature asian team leader asked some general questions and some technical with full proficiency... Do not panic just be relax and be prepared on C++...
