The head of the team called me for a one hour phone interview. Mainly questions came from C++ and Matlab. Not coding, but conceptual questions, followed by some standard questions - where do you see yourself in 5 years, strengths, weaknesses etc. Pretty basic. C++ questions were very simple - mostly things like explain polymorphism, explain OOP to a layman, what is the difference between ++i and i++, how does switch case work. From matlab, matrix manipulation, what do you not like about matlab and want to change.
