Startups > Venture Capital > Consulting --- Preparing for interviews with McK Digital as experienced hire

Hi everyone,
I'll be interviewing with McKinsey Digital (Italian office) in 2 weeks.

Does anyone have any pointers on where I can find Digital cases?

I know that this question has already been asked but I was hoping someone might have found something..

Ciao,
Eddie

Hi,

I have dozens from a range of case books and would be happy to case you in some!

I also recommend 1) Looking through PrepLounge along search words such as "IT", "Digital transformation","Agile", etc. and 2) Scouring casebooks for those with a focus in IT.

Best of luck!

Hi,

There will be a mix of regular and IT cases. For the regular cases on preplounge will be most helpful. For the IT cases, I recommend reading the articles of the consulting companies about these topics on their websites (Hundreds of them if you google by key words "agile", "Digital", at McKinsey, BCG or Accenture)

Feel free to reach out if you need help with digital case prep.

I have not seen any digital cases online. But here is a list of potential topics you need to know. It is a full list and looks scary but they test a lot of these concepts depending on the particular role:

  • Basics (computational thinking, sorting, data structures) - they never ask directly but understanding will help with the other topics)
  • Database design (Centralized vs decentralized, sharding, factors influencing the number of replicas - the volume of data, future scale, growth, data structure, desired speed, etc)
  • Technology stacks (front, back,api, database, etc)
  • Cloud (cloud vs own servers pro and cons, uptime % SLAs, load balancing, etc)
  • Server storage - major cost buckets - remember about additional replicas and cooling electricity costs
  • Security (encryption basics, public keys, password change policy, cloud security and encryption on your computer)
  • Agile and development (Agile principles, Environments: Developing, testing, production, Native apps / web apps / hybrid apps, etc)
  • M&A and IT (Will it be one system or two systems? Is it "Adopt and go" approach or we take the best of both systems and create a new one? Integrate now, innovate later? Or Innovate now, when you have time?)
  • IT strategy and Digital transformation (Similar to M&A)
  • IoT (Mainly the use of IoT in operations - Process steps completion, measuring temperature, maintenance measurements, other measurements, predicative algorithms, etc)

Good luck!

Hi Eddie,

what I have heard from people who applied to McKinsey Digital is that they were basically given the standard cases but with a focus on digital technology. So by practising the standard cases, you should be fine. The important aspect is that you have insight knowledge about current digital trends, but I assume you have otherwise you wouldn't have applied to this practice.

Good luck!

Cheers,

Daniel

Thanks for the answer Daniel. I was hoping someone had these cases "with digital focus" to share. I'm curious to see what topics are in there...
