Tuesday evening we drove up to Cambridge, where I had an interview the following day with a consultancy company. I have to say I did not have a good night: the bed was small and lumpy, and the sheet did not properly keep the blankets off - when will hotels get their act together on duvets? Strictly speaking it was not an interview - I was to turn up the next day at 10.30 to take two screening tests. I whiled away the time in the hotel lounge after breakfast listening to ‘The Well-Tempered Clavier’ and feeling increasingly nervous. I was not expecting these tests to be easy.
