I applied online. The process took 8 weeks. I interviewed at CIL Strategy Consultants (London, England) in Nov 2025
Interview
3 rounds - market sizing, short case, manager interview. They give you a mentor at the start to support you with the process, which is helpful. They specialise in CDD so expect to justify what sets them apart and why it interests you

I interviewed at CIL Strategy Consultants (London, England)
Interview
First-round virtual case study followed by two in-person rounds on the same day. First round consists of a market sizing within a short case, second round a standard case, and third round with the Partner and Director is where you'll need to be more creative
I interviewed at CIL Strategy Consultants (Chicago, IL)
Interview
The interview felt fair and well-structured overall. The questions covered a reasonable range of topics, and there was enough time to respond thoughtfully. The interviewers were professional and gave each candidate equal opportunity.
I interviewed at CIL Strategy Consultants (London, England)
Interview
Got my way to the second round interview. Passed the first round which was a primarily mathematical case study with classic market sizing questions (the mentor was really helpful for this). The second round casing was much more qualitative, and found that difficult - make sure to pay attention to the whole text
