Company: Pinterest

Role: Product Manager

Category: Behavioral & Leadership

Difficulty: medium

Interview Round: Other

Describe a decision you made that turned out to be a poor one, what you took away from it, and a later decision where that lesson led you to a better choice. ```hint Separate the call from the outcome Pick a decision whose flaw was in how you made it, not only in how it turned out. That gives you a lesson about your own process, and a later decision where you can show the changed process at work. ``` ### Clarifying Questions - Should it be a decision I made and owned myself, or can it be a team decision I influenced? - Does "poor" mean the result was bad, or that the way I decided was flawed even if things worked out? - Should the better decision be a separate, later situation where I applied the lesson, or the way I corrected this one? ### What a Strong Answer Covers - A decision the candidate clearly owned, with its context, the options and the reasoning used at the time - Honest consequences, how the candidate noticed the problem, and what they did to limit the damage - A root cause located in the candidate's own judgment or process rather than in bad luck or other people - A concrete change in how the candidate decides, and a later decision where that change produced a better result ### Follow-up Questions - How did you realize the decision was poor, and how long did that take? What would have told you sooner? - How did you explain the mistake to your manager and to the people it affected? - Has the lesson ever pushed you too far the other way, for example by slowing a decision that needed speed?
