Who is this for?
Candidates who freeze on behavioral questions — you can solve cases but when asked about yourself you struggle to give convincing, structured answers.
Those with good stories but poor structure — relevant experiences that lose impact due to lack of structure, too much detail, or weak connection to the competency being evaluated.
Experienced professionals struggling to select relevant stories — you have many situations you could share but don't know which ones are most relevant for each question type.
Anyone who passed cases but failed FIT — if your case went well but you didn't get an offer, the behavioral portion was likely the reason. This book shows you what went wrong and how to fix it.
What's inside?
85 real behavioral questions by category
Organized across 8 categories: leadership, teamwork, achievement, failure, influence, conflict, adaptability and motivation. Each question includes what the interviewer is actually looking for when they ask it.
7 answer templates adapted for consulting
STAR method variations designed specifically for strategy consulting interviews. Not generic STAR — each template is adapted to a specific competency type and question format.
14 skill areas with evaluation criteria
The 14 competencies McKinsey, BCG and Bain actually evaluate in the behavioral portion. For each one: what they look for, positive and negative signals they detect, and the level they expect by role.
How to select and adapt your stories
A system for mapping your experiences to the competencies being evaluated and adapting the same story to different question types without sounding repetitive or forced.
Common mistakes and how to avoid them
The patterns that cause candidates with good stories to receive negative evaluations: from answers that run too long to stories that demonstrate the wrong competency entirely.
How this book works
Preparing for consulting interviews isn't just about solving business cases. Firms like McKinsey, Bain, and BCG now dedicate up to 50% of the interview to evaluating who you are: your experiences, leadership, how you think, and how you communicate.
This is often referred to as the fit interview or PEI (Personal Experience Interview) — and it's where many technically prepared candidates lose the offer. Not because they lack experiences, but because they can't tell them with clarity and impact.
This book gives you a complete system: 85 essential questions, 7 story-building templates, and a framework for mapping your experiences to the competencies being evaluated. It's not about memorizing answers — it's about building stories that demonstrate exactly what interviewers are looking for.
This book is for you if:
- ●You're applying to strategic consulting firms and want to stand out in the personal part.
- ●You have strong experiences but don't know how to tell them clearly and with structure.
- ●You want to excel in the full process, including the personal and leadership component.
- ●You're looking for a practical guide with structure, content, and depth to prepare the Fit interview.
