Continental Engineer interview questions

There was a technical interview with 2 head of departments followed by an HR interview with a senior HR executive. The technical interview was conducted in a very friendly manner. Where I failed to answer, they would help etc. The questions were easy. Simple questions about C, C++, UML, OOAD and Java. The HR interview was like a grilling session. Mostly questions about how to manage in the international situation of the workplace, people from all around the world and how to fit in. How to deal such a situation and so on. Asked in a very hostile manner.
