Interview is 3-4 rounds. Questions are half technical (one person threw a case-study at me) and half fit. I think is you're able to convince the person that you're smart and not too timid, it should be easy for you to get the offer. Also, one way to fail for sure is to talk about something you're not very solid on. I've heard senior guys come out of a room and talk about how the interviewee went down a path he didn't fully grasp.
