BCGX R3&R4 Interview

You're in the right place and great to hear you're progressing to R3 & R4 with BCG X!

The BCG X interview process (formerly BCG Digital Ventures and BCG Gamma) typically combines elements of traditional case interviews with a stronger emphasis on product thinking, engineering depth, and collaboration, especially in later rounds like R3 and R4.

Here’s what to expect:

Round 3 – Engineering Product Interview

• May include a case-style discussion focused on product architecture, scalability, trade-offs, or technical design decisions
• You might be asked to prioritize features, assess technical feasibility, or walk through how you’d build and ship a product
• Clear, structured communication is key, even in technical discussions

Round 4 – Partner Interview

• Tends to be less technical, more focused on strategic thinking, stakeholder alignment, and leadership potential
• You may be tested on your ability to influence decisions, handle ambiguity, and bridge business and tech
• Expect behavioral questions and potentially a high-level business case with a digital lens

General Tips:

• Prepare for cases with a digital/product twist (e.g., launching a new platform, scaling infrastructure, improving user conversion)
• Be ready to discuss your past engineering decisions and how they created impact
• Demonstrate collaboration and product mindset, not just technical execution

You're nearly there, let me know if you’d like to run through a mock or tailor your prep for a technical-product hybrid case.

Hello there!

That depends to the role you’re applying to. Would it be regular consultant within BCG X or a technical role (eng, designer, data scientist, PM?). If it is a technical role, you’ll be given a tech assessment, followed by case interviews (similar to a business case, following the same logic but with a focus in BCG X scope) and behavioral interviews. All of these parts are critical, the technical assessment being the first filter.

Happy to assist you with the case and behavioral interviews, if you would like to know more details, I’m one message away!

Best,

Mari

One other piece of advice - reach out to a couple of people who are now working at BCGX and ask them for advice on the application process. You don't need to ask them directly about the questions they received in the interview as this will kill the discussion, but for advice on how to best prepare and what worked specifically for them. 

Best,
Cristian

Hi,

I saw you had a comment unanswered: Hi! It's a designer role. I've passed the portfolio, and technical (design+biz) case study, now moving to R3 and R4! 

I'm just wondering what could the format be as I've realised there are a lot of case studies for normal strategy consultants. So, I was wondering in my case will there be more case studies for the following rounds.

Normally there will only be the two rounds (R3 and R4).

The format will be a normal business case but with a technical element. R4 with the partner will usually be a light case with technical elements but they will ask deeply about FIT.

I would however HIGHLY RECOMMEND that you reach out to current employees to ask them about the process! You can explicitly say you're not trying to find exact questions but general gist of the process.
