How to approach ambiguous multiple-choice questions (MCQs) questions in BCG Case Chatbot?

Question

Hi everyone,

I’ve been practicing with the BCG Case Chatbot and ran into a recurring issue with some of the MCQs. In several cases, the questions feel somewhat ambiguous, and more than one answer seems logically defensible depending on how you interpret the context.

For example, I had a case where two companies were considering a joint venture to invest in 5G infrastructure. The question was: “What are the risks?” The answer choices were:

Regulatory risk
Risk that one company may not want to continue investing due to lower calculated profitability
Decline in phone sales market
Interdependency risk

There were 3 correct answers out of 4. I selected:

Regulatory risk (correct)
Interdependency risk (correct)
Decline in phone sales market (incorrect)

However, the chatbot expected the third correct answer to be the profitability misalignment between partners.

My challenge is: in the moment, I had a logical rationale for my choices, and I could justify them verbally in a real interview. But the chatbot marked my answer as incorrect because it didn’t match the “expected” set.

My question is:
How should I approach these kinds of ambiguous MCQs in the BCG chatbot? Is there a framework or mindset to better identify which answers the system considers “correct,” even when multiple options seem reasonable?

Would appreciate any tips from those who’ve encountered similar issues!

Hi Rada,

In general, the BCG chatbot is intentionally designed to include some ambiguity, so it’s normal to come across questions where more than one answer feels defensible. Also, keep in mind that you don’t need to be perfect to pass; the bar is relatively low, so missing one or two tricky questions shouldn't be a deal-breaker

In your specific example, I think the key is to stay very close to the wording of the question. The question is about the risks of a joint venture, not the broader market. Regulatory risk, misalignment between partners, and interdependency are all directly linked to the JV itself. On the other hand a decline in phone sales is a general market risk that would affect the company regardless of whether the JV happens or not.

So the main recommendation is to be very precise in how you interpret the question. A useful trick is to quickly paraphrase it in your head: “What are the risks specifically tied to entering a joint venture with a partner?” That usually helps filter out broader, less relevant options

Hope this helps. If you’d liketo practice together or go deeper on this, just let me know.

Hey,

Let me be super-honest with you: I spoke about this with a few MBA friends who now work at BCG and they told me that they don't love the chatbot either, so you are not alone in complaining :)

What I would do is trying to write down the clear logic link between the different risks and the investment. Here:

Regulatory risk: if the regulator limits this ex-post (e.g., up to a certain market share, or limiting usage), the value of the investment is likely to be reduced.
1. Very clear link -- good!
2. Can we falsify this? If regulators set limitations, our investment is not likely to be reduced. I can't -- this confirm my selection
Interdependency risk: if the other operator changes their strategy, exits a specific geographical market, etc., the investment is likely to lose value (or, I might have to cover more OPEX).
1. Very clear link -- good!
2. Can we falsify this? If the other operatore changes their strategy, our investment is likely not to be reduced. Well, it technically can, but I really have to find edge cases to falsify the hypothesis (e.g., we have more 5G supply for our clients and we can monetize this) -- I would keep it
Risk that one company may not want to continue investing due to lower calculated profitability: this feels very similar to the interdependency risk. Very clear link (as above) and hard to falsify -- same as above
Decline in phone sales market: What matters is the evolution of the demand of 5G, that does not logically require phone sales to grow.
1. Weaker link -- I would not select this!
2. Can we falsify this? If the phone sales decline (e.g., people do not buy iPhone 18 but stick to 17), the 5G usage is not directly impacted. I say yes -- so I would confirm the 'no selection'.

Again: overall, I agree with you on how this exercise can not be treated deterministically (i.e., prompt x always and only leads to y in any case and with any realistic assumption). However, I still think that the idea of writing down the relationship and trying to falsify it might help :)

Best,
