The most vivid stories about a project usually don't come from the people who carried it. A smooth narrative with a clean arc, polished phrasing and not a single stumble is almost always a sign of distance, not depth. Because someone who was genuinely inside it remembers differently: in a tangle, with detours, with "oh, and there was this whole mess on the side." Real work doesn't come back to you as a presentation.
The easy one: the liar
You can see it even against the obvious case. A liar is easy to spot in an interview: he flounders on details, trips over terms, and two or three follow-up questions make the picture clear. He's the simple one.
The hard one: the one who isn't lying
The genuinely difficult one is the one who isn't lying. The one who sincerely believes he did more than he did. He isn't deceiving you, he's deceiving himself. No tension, no darting eyes, no contradictions — just the calm, honest confidence of someone who spent years next to significant work and, somewhere along the way, quietly began to consider it his own. And he talks about it smoothly, precisely because he's recounting the big picture rather than his own scars.
It isn't ill intent. It's memory. You were in the room when a hard call was made, and a year later memory quietly rewrites "I was present" into "I was one of the people who decided." Presence rounds itself up to participation, and the person recounts, in complete sincerity, something he never actually did.
Presence rounds itself up to participation.
You can't filter out this candidate with ordinary questions: he says the right things in the right words and moves confidently through the names of technologies. And the listener falls into his own trap — mistaking a smooth delivery for real depth. The gap surfaces later, when a task harder than the usual one suddenly stalls.
How to tell them apart
There's only one way to tell two such people apart: the structure of what they remember.
The one who stood nearby remembers where things landed: the outcome, the decision, the stack. Smoothly, because that's the ending. The one who did the work remembers the road: what they discarded and why, which compromise they had to swallow, what broke after that decision and what it cost. Tediously, because those are the details. The first recounts the ending of the film. The second remembers how it was shot — including all the takes that never made the cut.
So a dull, meandering account weighed down with caveats is often the best sign that a person was actually there. Telling it apart from a smooth, sincere delusion is, in fact, the work you hand to us — so you don't end up doing it yourself in month two.
