A prospective supervisor is interested in me, and has asked me for programming interview. As I have been told, his research group does a lot of system programming, and he is seeking a good programmer.
I have no industry experience in programming, though I have programmed for assignments, projects, and a Master's thesis. I know that, as a computer scientist, it is essential to have good programming skills. I tried to search for some tips about programming interviews for prospective PhDs, but could not find anything.
Does it differ from industrial interview? Did anyone have similar experience? Any references or tips?
