Angela Duckworth’s Grit: The Power of Passion and Perseverance (2016) made a persuasive case that long-term success owes as much to sustained effort as to raw talent. In her studies of West Point cadets and spelling bee finalists, the ones who stuck with a goal often outlasted peers who looked more gifted on paper.
Most hiring managers say they value that persistence. Then they try to find it in a thirty-minute conversation. The ritual survives because it’s familiar, not because it works.
The flaw isn’t the clock. It’s the design. Interviews reward polish. Candidates rehearse, and the room is set up to keep difficulty out of sight, which makes it a poor place to learn how someone behaves when things get hard. A candidate who interviews well may simply have practiced interviewing, while one who stumbles may have spent that time doing the work.
Grit leaves traces: the years someone stayed with a hard problem, the goals pursued without an audience, a failure absorbed and worked through. You can’t see those in the room. You have to dig for them, and digging takes more than one conversation. It also takes some humility, because grit overlaps heavily with conscientiousness, and a long tenure is a lead, not proof.
Idea for Impact: Use the interview to find the evidence, then confirm it elsewhere. Ask, “Tell me about a goal that took more than a year. When did you want to quit, and what kept you going?” Then press for specifics: dates, who else was involved, what changed. A rehearsed story thins out under detail, and a real one gets richer. Check it against a reference or a work sample before you rely on it.

Go deep. You can’t recombine what you’ve only skimmed.

Arguments can be productive, but certain behaviors always derail them. Over the years, I’ve learned what really gets under my skin when trying to communicate:
When Howard Schultz returned to Starbucks in 2008, the company had lost its way. Growth had diluted identity. Speed had replaced craft. The brand that once promised connection now delivered convenience and little else.
