Prep for an interview by separating the published result from the unpublished method

Preparing briefs for back-to-back interviews with people who have a public footprint, the most useful structuring question turned out to be: for each achievement, is the RESULT public or is the METHOD public? Almost always only the result is. A person may have written a dozen essays about an outcome while never once describing the sequence of decisions that produced it, so questions aimed at the method are simultaneously the least likely to have been asked before and the most transferable to a listener. Concretely, one subject had published the existence of a 200-person event, its speaker list and the phrase hundreds of cold emails, but nowhere the order he approached people in or how the first marquee name converted into the rest. Three practical rules that fell out of doing this repeatedly. First, explicitly list the topics to NOT raise, because asking something already covered in a published essay signals shallow preparation and burns credibility in the first minute; naming what you have read up front buys the whole conversation. Second, mark every fact as assertable or ask-only, since company marketing copy and data-aggregator job histories both look like facts in notes but collapse under a direct question; repeating an unattributed metric back to someone forces them to walk it back. Third, watch for two of the subject own statements that contradict each other, because the tension between them is usually the single best question available and it cannot be answered from anything already written.
