My initial interview was over the phone. We stepped through the interview basics really, bit about the role, why the position became open, then we delved into questions about my experience and attitudes, overall I felt positive about the interview experience.
The second interview was face to face at betfair. The first guy was very abrasive and described the culture as somewhere that people will try and catch you out, try and pull the wool over your eyes (akin to his exact words), it came across as an environment that was utterly unsupportive. The next two guys were more pleasant, but only just. I was asked back for a third interview but declined, the impression I left with meant there was no way I wanted to join a team that seemed more like a politics laden snake pit.
