Bloomberg Mobile Software Engineer interview questions

Was asked to register with them. Got a call to take an online C++ test. C++ test was 1 hr multiple entry, with questions covering advanced C++ and STL It was a fairly average test , got a scor of 3.06 (you get a interview call if you are above 3.0) I was asked to prepare on Exception handling and STL for the telephonic interview The interview got postponed and someone else took the interview, and the questions were different. and not on STL Some of the question were 1> What does the compiler do if i only declare a class as Class A { }; 2> Some questions on copy constructors. The point is these questions are tricky , as its telephonic and not on paper and you really cant visualise what the question actually is ....so be prepared with a paper and pen...and juss keep on writing whatever you hear
