ONLINE GAMES
You hear “BCG online case.”
Then someone says “Casey.”
Someone else describes a chatbot.
Another candidate remembers a different format.
So you start researching the interface.
That may be the least important part.
BCG recruiting processes can vary by office and candidate group. In some current recruiting processes, BCG describes its Online Case Experience as an interactive business case guided by Casey, a chatbot.
But whatever appears on your screen, the underlying problem is more familiar.
You still need to turn information into a business decision.
The chatbot changes the conversation... but not into a normal case
In a live case interview, the interviewer gives you signals.
A raised eyebrow.
A follow-up question.
“Anything else?”
A pause when you have missed something.
Casey does not give you the same human feedback loop.
That matters.
You have to recognize for yourself when your structure is drifting or your answer is not addressing the question.
The silence is part of the difficulty.
You may know how to solve the business problem but still struggle with the format because nobody is helping you calibrate in real time.

PhDs often love the data... right before the data becomes the trap
An exhibit appears.
Rows. Columns. Percentages. Maybe several things you could calculate.
This feels comfortable.
So you start analyzing.
And analyzing.
Then one minute later you realize you never asked the consulting question:
What am I trying to decide?
In research, interesting information can justify investigation.
In a case, information earns attention when it changes the recommendation.
That distinction is small.
It changes everything.
| What you notice | PhD instinct | Consulting turn |
|---|---|---|
| One unusual number | Investigate why | Ask whether it changes the answer |
| Several possible calculations | Calculate them all | Prioritize the decision-driving one |
| Incomplete data | Resist concluding | State the assumption and move |
| An attractive hypothesis | Gather confirmation | Look for evidence that could disprove it |
The case is not rewarding curiosity alone.
It is rewarding directed curiosity.
So is Casey easier because nobody is watching you?
This is the deceptive part.
No interviewer means no awkward silence while you structure.
No one sees you scribbling.
No partner waits while you divide 37 by 4.8.
That sounds relaxing.
But the interviewer also cannot rescue you.
They cannot clarify a misunderstanding the way a human sometimes can.
They cannot notice that your logic is strong even though one calculation went sideways unless the assessment captures it.
Less social pressure can mean less conversational support.
That is why practicing only live cases can leave a gap.
You need some practice where the structure, calculation, and synthesis must survive without another person nudging you forward.
Do not prepare for the bot. Prepare for the decisions.
The exact assessment experience can change.
Your preparation should survive that change.
Get comfortable with:
- structuring quickly
- interpreting exhibits
- doing clean arithmetic
- choosing which calculation matters
- stating a recommendation from incomplete information
- moving on after a question instead of mentally relitigating it

Then stop obsessing over whether one screenshot you found online matches what you will see.
Interfaces change.
The deeper test is remarkably stubborn.
Can you look at unfamiliar information and decide what matters before the clock does it for you?
That is the case.
Chatbot or not.
