I was interviewed by two men in a non-formal environment, there was no one from the HR department. They seemed to be disinterested and in a hurry to get the interview over and done with. When I answered questions, they wouldn't even wait to hear the answer and were dismissive. The whole process was rushed and unpleasant.

An easy, straightforward process includes 1 call with a recruiter, 1 hour call with a hiring manager, and 2 short calls with top management. Situational questions and more of a conversational style.
