I'd previously had a phone chat with Colin, one of the founding members, and was subsequently asked to come in for an reasonably informal interview with Colin and Sanjay join us briefly.
It was held at their Leeds office and in all was a great experience. Colin is a great guy and you get a real sense of team effort from the organisation. The room was a touch hot as there wasn't any ventilation but Colin apologized for it from the outset and suggested I took my suit jacket off, also there was a plentiful supply of water.
It really was more of a friendly chat about the role and my mix of skills & experience. About 5 days after the interview Colin did follow up with a nice personal email providing an update which connects with their personal values.
In this instance unfortunately whilst Colin felt I would have been good and succeed in the role, unfortunately for me there was another candidate who pipped me at the post with technical experience. I really hope it works out for that candidate and the company it would have been an excellent place to work.
