The interview was quite relaxed and open, starting with questions regarding CV, previous experience, relevant skills, and finally a 15 minute "speed of thought" test. The whole process lasted just shy of an hour. A basic overview of the operation was given, though no specific details. I felt like the interview passed pleasantly and comfortably - possibly not a good sign. I was informed that I would be contacted either by telephone or email by the end of the week, with a view to a start time the following Monday morning.
I heard nothing by Friday 5pm, so I called the office, and was advised that I would most certainly receive a call "soon", and that the chap who interviewed me was now on holiday. I am still waiting for a call a week later.
