Investment Banking Prep Pack - Your opinion ?

They are excellent value relative to the $. i think that the behavioral questions are pretty much what you should expect from any finance interview, and you shouldn't have much difficulty in drawing from your experiences to answer them. The technicals typically don't usually sway from what you see in the guides, but the problem that i see a few folks have when I'm interviewing the is that they memorized rather than conceptualized, and by that I mean that they only looked at the questions on the guides without application. (ex. how does a $10 increase in depreciation affect the financial statements can be altered to speak to a bevy of different modifications, to which the model that the guide comes with addresses)

overall, these are a succinct guide of pretty much most of the questions you will see in an investment banking interview. at the summer analyst/analyst level, I wouldn't recommend using much more than this and brushing up on the markets so that you can have an intelligent dialogue. with respect to the MBA level, this is a bit out of my league :D, as i've only been in the industry for a few years. (there may be a few case studies based on what a few folks mentioned).

overall, i endorse the guides. great value, and for 100 dollars, you won't find much better materials. All the best!
