Questions, answered.
Everything about the BCG Online Case — and how to prepare for it.
About the BCG Online Case›
What is the BCG Online Case (the “Casey” chatbot)?+
The BCG Online Case — often called Casey, after the chatbot that runs it — is BCG’s digital case-interview assessment. Instead of a live interviewer, a chatbot named Casey guides you through a single business case, asking 8–10 questions in sequence and finishing with a short recorded video. BCG uses it to screen candidates early in the recruiting process, so a strong result is often what stands between you and a first-round interview.
What’s the format, and how long does it take?+
You get one business case delivered by the Casey chatbot: roughly 8–10 questions in about 35 minutes, followed by a 1-minute video recommendation. The clock runs continuously — you can’t pause, and once you submit an answer you can’t go back to change it. It’s deliberately fast and high-pressure, much like a real case interview.
What types of questions does Casey ask?+
Casey mixes several formats: a structuring or data-selection question to open, then multiple-choice (single- and multi-select), number-entry questions that need quick case math, and short written answers. You’ll read charts and exhibits to pull out the right figures, and you close with a 1-minute video pitch to the client. Comfort with fast mental math and exhibit interpretation makes a big difference.
Can I use a calculator?+
Yes. The BCG Online Case allows a simple calculator and pen & paper, so you can focus on setting up the case math correctly rather than doing everything in your head. Speed still matters, though — a calculator only helps if you know which numbers to compute. Practise the same way: keep a basic calculator and scratch paper beside you as you run our cases.
How hard is it, and what score do I need to pass?+
It’s challenging — time pressure, case math and exhibit reading combine to catch people out. BCG has never published an official pass mark, so nobody can say for certain what’s required. As a rule of thumb, aim for around 80% to be on the safe side — the further above that, the more comfortable your margin. Our simulator scores every attempt, so you always know where you stand against that bar.
Is there an official BCG practice demo?+
As far as we’re aware, no. BCG doesn’t provide an official practice simulator or public demo you can rehearse on in advance. At most you might receive a brief format note with your invitation, but nothing that lets you actually practise a full case — which means the first realistic run most candidates ever get is the real exam itself. That’s the gap PrepCatapult was built to close.
The PrepCatapult simulator›
What is PrepCatapult?+
PrepCatapult is a leading consulting-interview preparation platform, founded by a team of seasoned ex-MBB strategists and final-round interviewers. It helps aspiring consultants break into top firms — from application strategy and core-skill drills to realistic case simulation and 1:1 coaching. This BCG Online Case (Casey) simulator is part of that wider platform, built to give you the most realistic Casey practice available anywhere.
How is PrepCatapult’s simulator different?+
Our Casey simulator recreates the real experience closely — the chatbot flow, timed questions, live exhibits and the 1-minute video pitch — so you can practise in a close-to-real environment instead of just reading about it. Every case is carefully curated and peer-reviewed to match the style, difficulty and question mix of the actual assessment, and each run is scored so you get honest feedback the real test never gives you.
What feedback and scoring do I get?+
The moment you finish, you get an instant scored review. Your performance is broken down across the core dimensions BCG tests — including problem structuring, quantitative analysis, exhibit interpretation, critical thinking, business judgment and synthesis — alongside worked solutions and a personalised prep plan showing exactly what to work on next.
Who writes the cases?+
Every case is developed and peer-reviewed by a team of seasoned, ex-BCG final-round interviewers — the people who sat on the other side of the table. That means the scenarios, question types and scoring are calibrated to what actually separates a passing candidate from the rest.
Pricing, access & the essentials›
How much does it cost, and how do Case Credits work?+
You buy Case Credits, and each credit unlocks one full case — the complete timed assessment plus its full scored review and worked solutions. Pricing is simple: €19 for a single credit, €49 for a pack of 3 (about €16 each), or €99 for 10 (about €10 each). There’s no subscription — credits sit in your account until you use them and never expire, so you can spread your practice over time.
Can I get a refund?+
Because a Case Credit delivers the full assessment and its complete review the moment you start, purchases aren’t refundable. You get real value from the very first question — the realistic practice, your scored breakdown and worked solutions are all yours immediately. Your credits never expire and your reviews stay in your account for you to revisit any time.
Is PrepCatapult affiliated with BCG?+
No. PrepCatapult is an independent preparation platform and is not affiliated with, endorsed by or connected to Boston Consulting Group. Our cases are designed to be realistic and BCG-calibre in style and difficulty, but they are entirely fictional — all companies, people, figures and scenarios are invented, and any resemblance to real organisations or data is purely coincidental.
How does refer-a-friend work?+
Love it? Share it. When you refer a friend and they buy, you earn a free Case Credit and they get a discount — so you can keep practising while helping someone else prepare. You’ll find your personal referral link in your account once you’ve signed up.
