Fit is where many senior hires succeed or fail, and it is the hardest thing to judge in a one‑hour interview. A candidate can have the right experience on paper and still be wrong for a family that makes decisions slowly, values privacy above all, or expects to be closely involved. A few deliberate steps make fit much easier to see.
Define "fit" before you meet anyone
Fit only means something once the family has described itself honestly. How quickly are decisions made, and by whom? How involved is the principal day to day? Which family members will the new leader work with? What does the family expect to stay private? Writing these answers down first gives every interviewer the same standard to judge against.
Ask about real decisions, not opinions
Most candidates can describe good judgment in general terms. Better questions ask for specific examples: a time they disagreed with the person they reported to, a decision that turned out to be wrong and what they did next, or a time they held confidential information that others wanted. Specific answers are much harder to rehearse.
Notice how candidates talk about their current firm
Discretion shows up in the interview itself. A candidate who shares details about their current employer's positions, clients, or internal disputes will likely do the same with yours. The strongest candidates explain what they did without revealing what they shouldn't.
Look past style to judgment
Candidates from trading firms often come across as direct and fast‑moving. That is usually the culture they come from, not a sign of poor fit, and many adapt quickly to a family's pace. The reverse also holds: a polished presentation is not the same as good judgment. Focus on how a candidate reasons through a problem, not how smoothly they talk about it.
Meet more than once, in more than one setting
A single formal interview shows one side of a person. A second conversation with another family member, an informal meal, or a working session on a real (anonymized) problem the office faces reveals far more about how someone thinks and how they will work with the family.
Take references seriously
Ask references specific questions: how the candidate handled a serious mistake, how they treated people who reported to them, and whether the reference would hire them again. With the candidate's permission, speak with someone beyond the names they provided. Done carefully, this protects the candidate's confidentiality while giving the family a fuller picture.
Be honest about the family, too
Fit runs both ways. Candidates who discover the real decision‑making process or family dynamics only after they start are the ones most likely to leave early. A candid description of the role and the family is one of the best retention tools a principal has.
