I was first interviewed by the HR person, then a general counsel from the Legal Department. The HR asked so many questions from information about my major to my experience that it lasted almost an hour, then the in-house counsel briefed me on job duties before asking more specific questions relating to my qualifications and experience. The second interview was conducted by another general counsel from Legal Dept. This interview focused more on the questions I wanted to ask him, and was more like a casual chat (well not so casual) than a formal interrogation. I felt quite relaxed that time... but who knows, it may be because the guy is actually nice.
