The author articulates very well the life of a consultant. I really reccomend University students take heed because there seems to be a disconnect between what the image of the job is, and the actual reality. I worked as a finance and economics consultant in electricity, water and gas. I did learn how to write properly (in plain English) and how to methodically solve problems, but you can learn these things from two books:

1) Style: Towards Clarity and Grace, and 2) The McKinsey Way.

I can't stress enough that eventually consulting becomes a vapid and soulless way to make a living.
