Many people only train on cases and neglect the personal experience part of the interview. Big mistake. It is as important as the case and will help the consultant determine a decisive question about your fit: ‘would I want to have this person on my team?’. The good news is that this part of the interview is more predictable than the case and thorough preparation will help you a great deal.
Contrary to common belief, the personal experience part of the interview is not a long monologue where you brag about your merits. This is not a bedtime story. What will happen is that you will be asked to give a very brief summary of the situation, after which a dialogue with the consultant will ensue. This dialogue will sometimes go into very small details such as what you did and how you felt at a certain points in time, what a certain person said to you, what their body language was like etc.
The part you can prepare is 2-fold:
The 1-2mn summary. Don’t reinvent the wheel and follow the STAR framework (Situation – Task – Action – Result). The situation, or context, should only be 3-4 sentences long, the result, only 1-2 sentences long. The bulk of the time shoud be spent on the tasks (a.k.a. challenges) and actions. Don’t forget to focus on your actions. Here is an example:
S: “During my senior year at university, I was elected captain of the rowing team”
T: “At the beginning of the year, as we started training, I observed 2 challenges: 1) some people were not following the training schedule and started to lag behind in terms of fitness level, and 2) we were facing a cash problem as the school had reduced our funding due to budget cuts”
A: “To solve the first challenge, I did 2 things: 1) I paired everybody up, mixing those who were consistently training and those who were not so as to motivate the latter to follow the schedule; 2) I built a tracker of all training performances such as rowing machine power output, max weights, max reps and updated each rower with their month-to-month progression. For the second challenge of cash shortage, I created a calendar featuring artistic pictures of the athletes and sold it in our school by visiting dorms door-to-door”
R: “With these initiatives, we soon reached an attendance level of over 95% to training sessions, saw record fitness progress for many of the athletes and raised over $10K for the club via the calendars”
The nitty-gritty details. For each challenge and actions, try to remember details such as names, conversations, reactions. They will be useful when the consultant will probe your story
