I don't believe in a one-size-fits-all approach with run-of-the-mill schemes. All my coachings are 100% personalized and take into consideration your specific individual situation.
A key issue I see with most candidates and many other coaches is a narrow focus on solely a few components out of many. More often than not, only personal fit interview, case interviews, market sizing and brainteasers are covered. Those are important components for sure - however, it's a too simplistic approach for a highly demanding role like a consultant. Therefore I cover in my holistic coaching approach many more areas as demonstrated in the graphic below [blurred for IP protection; obviously I will share all those components in my coaching sessions]. In combination with the before-mentioned basics, covering all those areas make my coaching candidates truly superior with an outstanding performance in their interviews.
Therefore, it's easy to answer what we will cover in a coaching session: It is whatever adds the most value to your prep at any given moment.
Typically, most candidates focus on (McKinsey) case interview prep - in this case, we will have a (McKinsey-style) case interview. Depending on your current level on performance, this case interview will be either run as a mock-interview, or more like a coaching-style session to explain the most important issues and fatal mistakes candidates make along the way, so that you don't need to learn it the hard way.
Time-wise, the case interview itself will usually last only around 25-40 minutes (depending on the case and on your specific focus/requirements). What might surprise you is that the feedback session after the case will consume roughly the same amount of time (so another 25 to 40 minutes), since we will recap the whole case interview in great detail from start to end - so that you know what was going well and therefore should keep it up, which aspects you need to imrpove and change, and even more importantly how to do it correctly.
Apart from the case interview, I am also coaching lots of candidates specifically on the McKinsey Personal Experience Interview (McKinsey PEI). Actually most candidates fail to get an offer from McKinsey not because of their case interview performance, but because of their PEI performance, and this is for sure the most underestimated part of the McKinsey recruiting process.
Please be prepared that you will receive 100% honest and brutal feedback. My job is to prepare you for your interviews and successful offers, and not to pamper your ego and make you feel comfortable. If you don't like this idea, it's probaby better if our paths will not cross. I am not telling this to make you afraid - but unfortunately more often than not, candidates think that they are well-prepared based on other coaches' or peer feedback - until they run a realistic case interview with me and understand the real-world performance expectations of MBB interviews.
