Casey Chatbot Case
One business case run by a chatbot: structure the problem, read exhibits, do the math, then record a one minute video recommendation. The closest thing to a live case, on your own, on the clock.

Casey, the CCA, and the Cognitive Test decide who reaches a live interview, and most candidates meet them cold. Practice each one in its real format, under the real clock, before it counts.
Which one you sit depends on your office and year. The suite covers all of them so you are ready whichever email lands.

An SHL-built screen that pairs behavioral working-style questions with a short, sharply timed numerical section. It goes out fast after you apply, so a coherent profile and quick math both matter.
A pure aptitude screen: numerical and logical questions at high volume against a tight clock, scored against your cohort. Speed and accuracy per minute are the whole game here.
BCG has largely retired both. Only prepare for them if your invitation explicitly says so. The guide has a short refresher for each, but Casey, the CCA, and the Cognitive Test are the current default path.
Every module runs against the same clock BCG uses, because the clock is what most candidates fail. You build the pacing before it decides your result.
Chat-led questions, exhibit reads, a video recommendation for Casey, forced-choice behavioral sets for the CCA. You rehearse the wrapper, not just the content.
Structure, data interpretation, math accuracy, and synthesis are marked the way BCG marks them, so your practice score means something.
I had never seen a video recommendation before. Recording ten of them in practice meant the real Casey felt like a Tuesday. Passed on the first try.
The CCA numerical section is brutal on time. Doing five full sets first meant I actually finished it with a minute to spare on the day.
My office ran the Cognitive Test, which almost nothing online prepares you for. Eighty questions in thirty minutes stops being scary once you have done it a few times.
Being able to see all three screens in one place saved me. I did not even know which one my office used until I started practicing here.
