What's the best consulting interview prep book for McKinsey

I have a first round phone interview, but I've only done banking interviews thus far. What can I expect and what is the best guide book to get in order to help me prepare??

Anyone ever used the WSO one? I used the M&I one for banking and it was great. Anyone like that for consulting?

MBB don't really give brain teasers; the closest thing that I encountered were market sizing questions (and a lot of them) as part of cases. A lot of boutiques do ask them, though. What worked well for me was going to GlassDoor and looking through the posted interview questions for the firm I was interviewing at, as these give a sense of how brain teaser-ish they can be and also give you some practice material.

One of those lights, slightly brighter than the rest, will be my wingtip passing over.

Source: I know tons of people who went to MBB or 2nd tier (think OW) consulting firms out of undergrad and, while I ended up going the finance route, interviewed for some consulting positions and thus went through my fair share of case interviews. These are the two best case interview books:

"Case Interview Secrets: A Former McKinsey Interviewer Reveals How to Get Multiple Job Offers in Consulting" by Victor Cheng

"Case in Point" by Marc P Cosentino

Practice, practice, practice cases. Have you friends in consulting give you mock case interviews. Perfect your strategy for those. That's the best possible thing you can do for those interviews, in addition to perfecting your answers to the "why consulting" questions. As far as going from consulting to IB or vice versa, I would not know as much about this specifically as other monkeys on here.

 

Thanks for the reply @zanderman

Will take a look at the 2 sources you have mentioned. Any information on how good/bad is WSO's own consulting interview guide ?

 

Thanks for the reply. I understand that and I will be getting my MBA. I was wondering whether the skills are transferable to some extent if lets say I work in consulting (or IB) for some years after MBA and then switch to IB (or consulting).
