The Risk of Over-Preparation
There is nothing unusual at all about an investigative interviewer preparing extensively for an upcoming interview. In fact, there are few situations where an interviewer can have too much information on hand before entering the room.
The danger arises when preparation becomes obsession—when the interviewer sacrifices spontaneity and flexibility in favor of rigid expectations. While “turning unknowns into knowns” is a valuable strategy, over-preparation can ultimately paralyze both the interviewer and the flow of information.
When Preparation Becomes Scripting
Are you “scripting” your interviews?
One clear sign of over-preparation is the tendency to script questions in advance—sometimes even sequencing them in a fixed order. The danger is that the interviewer becomes fixated on completing the list rather than listening to responses that warrant deeper exploration.
In these cases, the interviewer is no longer responding to the subject—but to their own plan.
Listening to these interviews can give the impression that the interviewer is simply having a conversation with himself, never truly hearing the subject.
Preconception and Tunnel Vision
Over-preparation often manifests as preconception.
A common hallmark is the overwhelming use of leading questions—especially short-answer questions that steer the conversation toward a single, predetermined conclusion.
If you were to map the direction of the interviewer’s logic, you would find it consistently pointing toward only one outcome. Any deviation from that path is met with resistance, and the conversation is redirected back to the interviewer’s intended track.
This occurs even when the subject’s responses clearly indicate that the dialogue should follow a different direction.
Frustration and Breakdown
Over-prepared interviewers frequently become frustrated when the subject does not conform to their expectations.
What begins as a structured interview can quickly deteriorate into verbal conflict, with little to no productive outcome. The interviewer, focused on proving a point, often misses opportunities to elicit valuable information.
Preparation vs. Flexibility
Preparation is essential—but not at the expense of adaptability.
The most effective interviewers recognize the balance between being prepared and remaining flexible. While preparation helps anticipate possibilities, it must not limit the ability to respond to what is actually happening in the moment.
Interviews are dynamic. They require the ability to shift direction, adjust strategy, and respond spontaneously to the subject and their behavior.
