Motorola Solutions interview questions

The interview consisted of hiring senior manager and a manager under him. It was pretty informal. I cant think of anything that was asked that stood out of the ordinary. Pretty much going over your resume and asking questions from it.

After submitting my resume I was invited for a call interview, followed by a face-to-face meeting at Motorola's offices in Kraków. There were several questions asked regarding software engineering. Looking back I would highly recommend reading books such as Scott Meyers' "Effective C++" series, McConnell's "Code Complete", Martin's "Clean Code", Reddy's "API desing for C++", or similar. Some of the questions asked: - write a function to reverse words in a C-like string (no stl), - write a function which implements atoi functionality, - what is a class invariant, - when to use "const" for passing arguments to a function, - what is a virtual function, - how to handle ctor/dtor which fails, - what is an abstract class/pure virtual fn, - what is a mixin, - whan it could occur that the function would not return to the place from it was called (hint: stack corruption), - what is a virtual dtor and why/when would you need it, - smart pointers, which do you know and what are they for, - c++ storage specifiers, - what can be the "static" keyword used for, - what is the anonymous namespace and what is it used for, - what is a reference, can you assign r-value reference, - how are post and pre incrementation operators differentiated, write sample implementations of both of them for a general type, - what is a template method, - what is stack unwinding, - what are the access specifiers for a class, - what is a difference between class and struct, - can you think of an example when your program would crash without reaching a main function, - how can you tell which shell are you running ona UNIX system, - write a function to reverse elements in a single-linked list, - explain different cast operators in c++, - is using global variables a good programming practice, does the same apply to singleton, - name two sort algorithms, assess their complexity, - what is a deadlock, - some pointer arithmetics problems, - variations on constness of pointers and types to which they point to, - what is a null object, - what is a pimpl idiom, - write a sample interface class, are the ctor/dtor mandatory, what will be the access specifiers for members in the interface class and the derived class which will contain the implementation, - design patterns (bridge, facade, proxy, visitor, chain of responsibility, factory method, abstract factory, ...) - what synchronization objects do you know which can be used in a multithreaded environment,
