Bristol Energy interview questions

My interview was scheduled for an hour but it did not last even 30 min. There were two interviewers. The first interviewer was rushing and was cutting my sentences. I couldn't complete most of my answers. The second interviewer didn't get any chance of asking me questions because of obvious reasons. I was confused about the interview process. I asked them what qualities they were looking for in an ideal candidate. To this, the first interviewer replied that I'm a perfect candidate and any firm would hire me easily but them, because "I might not fit in the position even if they hire me, as data mining is a backend job".. I have never heard anything such bizarre before.

They were over thirty minutes late for the interview. There is no foyer or waiting area so you have to awkwardly stand within a cramped area by the barriers. There are zero performance incentives which I found rather surprising and the office is one floor of a quite grim looking council building. Interviewers were very nice. They asked the standard competency based questions which you would expect but they also ask a lot of riddles designed to trip you up. You are either going to know these or you are not. I had expected visual pattern or situational logic puzzles that I had been asked at past interviews so this was unexpected. Ultimately, I had expected a very different package and interview from Bristol Energy so it was both a surprising and disappointing experience.
