Cognex Senior Software Engineer interview questions

I participated 7 interviews, which are with HR, section manager, software test, one of the experienced colleagues in our section, department manager and 2 managers from different departments which I will work closely.

Met with 3 engineers and the manager. Overall it was pretty thorough, covering multi-threading, class design, a mix of C# and C++. Very bright people. Another whiteboard question was to code a program that prints all prime numbers between 1 and1000. There were C++ questions about inheritance and polymorphism, some syntax, for example, given the expression *x++ = * a ++; Explain what happens when this gets executed.
