Quite an intense interview! A small group of interviewees (around 7) were taken to a meeting room and shown a video presentation, basically showing how big a company they were, how much money they have, etc. You then have to take a basic numeracy and literacy exam, as well as a separate exam in your specialist field (e.g. biology, chemistry, etc). After that there was a tour of the labs and lunch. After lunch, if you were successful in the exams, you then go on to have four separate interviews - 2 of which are technical and 2 of which are more HR-type interviews; in each case there are 2 interviewers present. Although the interview was intense, I found it a good experience and thought it was good that they really did want to recruit the best possible candidates.
