Hi Community,
I reached out to the recruiting team in London last October ('25) with the following question: "Is it correct that candidates first complete a standalone online (chatbot) case assessment before proceeding to any live interview rounds—that is, that advancement to interviews is determined by one’s performance on the online case?"
And here's the response I received: "In London, we no longer use the online case/chatbot, though after CV screening we will invite candidates moving to the next stage of the process to complete an online quantitative reasoning test. Following this, we’ll do another screen before determining who progresses to interview."
My questions then are as follows:
• Does the recruiter's answer still hold true in 2026?
• Is the quantitative reasoning test referenced above the same as the BCG HireQuotient Online Assessment?
• Is this a good resource to practice for this assessment or is it outdated? --> https://www.casebasix.com/courses/bcg-quantitative-reasoning-test
Which BCG online assessment does the London office use as a screener for EH roles?
Charles, that's a well-researched, targeted question.
The honest answer is that it's honestly impossible to know at this point. And do be rather sceptical about anybody claiming to have a confident answer.
They keep changing the recruiting process, and it differs esp between offices and roles.
Since you already have a connection to the recruiter, try to ask them directly for more information about the test. They say it's quantitative reasoning. Ask if they have any examples of this test or if they recommend any resources or can provide any indication of the format. Explain that this will enable you to be better prepared.
Last but not least, do bear in mind that these differences between formats can be significant but not huge. Effectively, they are all testing for the same things. So if in doubt, practice more of what you have access to already, having the confidence that it's directly or indirectly training the skills you'll be needing anyway.

Hi Charles,
Based on what we’re seeing recently, the recruiter’s answer still broadly holds.
For BCG London experienced hire roles, the office has indeed moved away from the standalone chatbot/online case as a default screener. The typical flow is CV screening, followed by an online quantitative reasoning assessment, then an internal calibration before deciding who progresses to live interviews. That process has been fairly consistent into the current cycle, though exact steps can still vary slightly by role and hiring needs.
The quantitative test they’re referring to is similar in nature to the BCG HireQuotient-style assessment, but it’s not always branded or identical across cycles. In practice, it tests speed, numerical reasoning, data interpretation, and logic under time pressure rather than full case-solving.
In terms of prep, the CaseBasix resource you linked is directionally useful for building comfort with the style of questions, but I wouldn’t rely on it alone. The format has evolved over time, so it’s better to treat it as supplementary practice rather than an exact replica. Timed SHL-style numerical reasoning, data interpretation drills, and GMAT Integrated Reasoning tend to be higher-ROI and more future-proof.
In short: no chatbot case for London EH, yes to a quant-style online screen, and use multiple up-to-date quant reasoning resources rather than any single course.
Hope that helps.
Best,
Evelina
