Interview
I applied online and got invited to a technical phone interview one week later. The next day I got invited to an inhouse interview two weeks later. Although they handed me a list of possible topics for questions stating C/C++, Java, Unix, runtime analysis, etc, I got mostly asked about C/C++ and pointers. In the 1-1 interview even only C.
