Barclays Data Scientist interview questions

phone interview with the recruiter, data challenge with the manager, onsite with 3 rounds. the process was very smooth, had a good experience with the interview process. Had a feeling that the candidate was chosen even before i interviewed onsite.

First and technical interview with two people from the company. Only one of them was mostly talking and they explained what the company do, projects, philosophy, etc. When they're asking questions about me, background and projects, the one of them really showed that I have not impressed him. He answered my questions very fast and sharp, saying that they have more interviews to do and did not ask anything else. The interview was supposed to be around 30min but after 20 they just hanged up on me, which I consider that very rude. I did not receive a feedback from the company or the recruiter.
