The book is a good reading. I was quite happy and I left confident to my assessment centre for a graduate scheme in one of blue chip companies. There, I realised that the book was written for a different (junior) audience. For example, the book states that in the group exercises you will have 15 minutes to read and prepare and 40ish to discuss. In truth, I had only 30 min to read a share document, discuss and present, which made the book's advice ineffective. As this book was written this year, so it is not matter of obsolescence, the author should have covered the type of assessment centres are going on.
