Continental interview questions

There are 2 stages of interview, Technical and HR. The technical interview lasted close to an hour. I was asked to introduce myself and were asked some technical questions on C++ verbally. I had to demonstrate my code and answers on the whiteboard. I wasn't shortlisted for the HR interview.

Initially contacted by HR for a telephonic interview. Performed it in a better way. Then I was called for a direct F-F interiview. German language is a plus but not necessary. Better english knowledge is the most needed.
