Case in Point
Any others worth reading?
This is the only one that's worthwhile. It's not perfect though (there are a couple of math errors in the solutions etc.)
Be aware that unlike the GMAT, a consulting interview can not be mastered by simply solving book exercises until you can do them in your sleep. In my experience, each interviewer will ask you some questions which you simply couldn't have been prepared for. Questions that require a display of your creativity and business judgement.
The best advice I can give you is to get a friend of yours - who preferably knows about consulting - to play the interviewer. If you manage to structure and solve a majority of the cases without your friend having to "pull" you towards the solution you'll be fairly well prepared for the actual interview situation.
