Depth of technology case interviews.

Hi all, 

I am currently preparing for my BCG Platinion interviews.
I assume, that more or less no candidate on entry level (IT-Consultant) is deep into every technology topic. 
I currently focused on expanding my knowledge in:

  • Digital Strategy
  • Cloud Migration
  • Architecture Modernization
  • Cyber Security
  • Agile Operation Model
  • Vendor Selection

I was wondering to what level of detail I must be prepared and if I am missing a topic.

Best regards and thank you in advance :)

Hey there,

Your topic list is very on point — it covers the core areas they often test. You’re right: at entry level, they don’t expect deep expertise, but they do expect structured thinking and basic fluency.

Make sure you can clearly explain: what the topic is, why it matters for a client, high-level steps, and typical trade-offs. That’s enough. For bonus points, add 1–2 examples or cases per topic.

Optional additions: IT cost optimization and data strategy come up occasionally, but not a must unless listed.

You’re on the right track, let me know if you want to practice a tech-style case!

best,
Alessa :)

Hello ! I think you are covering the key topics, and indeed, they don't expect you to be very deep, but they still expect a good level of knowledge. In some interviews I had, I was asked about a typical architecture for a data platform, so always good if you know how things work high level and know the most important vocabulary.

Hi there,

I'd take a step back here if I were you, and I'd first validate with the recruiter whether the interview will have a knowledge / technical component, and if so, then what is it exactly and what format will be used to assess it. 

Then you can be more tailored with the prep. 

Otherwise, you'll be boiling the ocean trying to cover all the possible concepts that you could come across, without knowing even what the granularity is at which they expect you to be familiar with them.

Best,
Cristian

Hello there,

Agree with Christian, before spending time studying, talk to HR to understand what level of expertise and in which areas you will be tested.

Good luck!

Best,

Mari
