How many types of cases will be asked within Mckinsey interviews (both 1st and 2nd rounds)

Someone asked on Oct 25, 2018 - 2 answers

In addition to the below list, are there any new types of cases would probably used within Mckinsey interviews for both 1st and 2nd rounds?

(1) Market entry

(2) Profitability or Revenue growth

(3) Competitive response

(4) M&A / PE investment thesis (including valuation like NPV)

(5) Capacity change (Is it the same as Operation?)

(6) Pricing

Considering recent hot topics about online, digital disruption, any other thoughts from experienced former Mckinsey interviewers and candidates having been through Mck interviews recently?

Many thanks!

I would add:

  • New product
  • Investment decision (not the same as M&A. Rather investment in new technology, business)
  • Operational math problems - (How to reduce the traffic jams on a bridge with certain output rate, capacity?)
  • Cost cutting
  • Digital (IT Strategy, IT investment, etc)

Finally, 30% of McKinsey cases are non-conventional. Here are some examples:

  1. Factors influencing the price (What are the factors influencing the price of oil? Factors influencing the price of real estate?)
  2. Macroeconomic cases (How will you improve life expectancy in a particular city? How will you decrease the unemployment?)
  3. Public sector non-profits (Increasing the revenues of a museum; increasing the revenues from tourism in a city)
  4. Redesigning the processes (How will you develop a new anti-monopoly regulation?)
  5. Non-profit investments (A billionaire is building a new school. What are the factors to look at?)

Ex-MBB, Experienced Hire; I will teach you not only the how, but also the why of case interviews

Off the top of my head, I can also think of non-profit fundraising and cost cutting / right sizing,

Operations could includte capacity change, logistics and lean manufacturing for example.

Really, there is a near infinite type of cases you can be given; a single word may alter the case completely. This is why I always teach the mechanics of the case (teach a man to fish) rather than focusing on a specific type of case (give the fish). Even as a consultant, you'll always do well the second time you have to work on the same problem - but this will pretty much never happen at MBB (it would at Tier2 and boutiques however)
