Mobile Applications Developer Interview

For my internship the most expected question was whether or

  not interfaces are supported in C++. I answered, no that's a Java only construct. The interviewer then asked if I was familiar with the virtual keyword in cpp, at which point I realized that you could create an equivalent of a Java interface in cpp by creating an abstract class with only pure virtual member functions. A great question. For my full time interview, there a few trickster questions regarding memory management in C/C++ (e.g. when and where will this program crash, where is the memory leak, etc.) as well as a few general binary search tree and linked list questions. Expect a few questions regarding running time and concurrency, but nothing too grueling.
