ecobee Technical Support Representative interview questions

Very efficient screening process. Initial interview was a short Hr screening. Followed by an online assessment which was very easy. One of the questions was listening to a call and answering questions based on the call. Followed by face to face with 3 managers. The face to face rounds was not very pleasant. Did not feel very comfortable as they were not friendly. Constant interruptions while answering questions and one of them was looking at the watch often, which gave me the clear impression that I’m not moving to the next round. I worked hard preparing for this interview spending several hours on researching about the company and its products , but whenever I tried to elaborate I was cut short as they don’t want to listen. My advice is don’t be over enthusiastic and just answer the question - they don’t care if you are not true - just need answers what they expect. Very disappointed.
