Talk about one of your favourite projects, its challenging aspects and how you approached them; how is C++ different from C; questions about memory management (stack vs. heap, which one is used when, which one works faster); reasons for which a program could crash; what is a constructor / destructor & how it works; discussion on hypothetical cases illustrating OOP principles (what would happen if class A has a private method and class B extends class A and so on); what is TCP/IP, how does it work; build a schematic protocol from scratch (only at conceptual level) - for example what would need to happen between the sender and the receiver to ensure connection reliability; how should the system respond if the receiver does not receive all the packages sent by the sender etc.
