Interview Preparation

We’ll help you prepare for the world’s most demanding interviews.

Our clients are some of the most selective firms in the world, using a combination of case and personal interviews to select fewer than one in 100 applicants. Drawing on our background with BCG and McKinsey, we have developed the Interview Boot Camp and Individual Coaching specifically to help you prepare for these demanding selection processes. More than one in three past participants received an offer from a top-three consulting firm – a significantly higher success rate than applicants who prepared alone.

We recommend the Interview Boot Camp to candidates interviewing for a Junior Consultant or Consultant-level role. We typically support senior candidates interviewing for Manager, Principal or Partner-level roles through Individual Coaching.

Our exclusive interview preparation material is also available to the public at, our online preparation service. It includes video lectures covering the key skills assessed by the firms, sample interview videos and access to private coaching with our former consultants. We provide this service free-of-charge for our preselected candidates.

Interview Boot Camp

This intensive 2-day weekend programme covers both case and personal interviews. It includes individual coaching sessions with ex-consultants, plenary sessions, group exercises and opportunities to practise interviews and connect with other preselected candidates.

The Boot Camp is taught exclusively by alumni of McKinsey, BCG and Bain, with at least one coach for every four participants.

Boot Camp participants have awarded the programme a Net Promoter Score of 95%, reflecting an extremely high level of satisfaction.
