The technology centre itself was quite a hassle to get to (25 minutes from Meldreth train station) and quite hard to find other than the centre itself looked quite interesting. The staff that lead the day seems to enjoy working there especially when they started talking about the products they have helped created. Overall the experience was less strict than I initially thought, as long as you show genuine interest in your subject and can hold a decent conversation with your interviewer there shouldn't be any problem. The group exercise was by far the most interesting part of the day (took me by surprise), so if you ever get to this point you can find out the surprise yourself. :D
