Interviewer talked almost non-stop the entire time and barely gave me a chance to respond or interject to discuss my own experience and how it was relevant, then decided not to move me on in the process. Was the test whether or not I was rude enough to talk over him?

A few back to back interviews on both finance, probability and programming questions. The questions are fairly comprehensive. The entire process was smooth and the interviewers were very helpful. And then received an offer within a week.
