"Tell me about a time you made a mistake as a manager. What was the mistake, how did you realize it, what did you do next, and what changed afterward? If helpful, you can use an example involving an engineering team shipping on a Meta surface like Facebook, Instagram, WhatsApp, or Ads Manager."
This question tests ownership, self-awareness, and leadership maturity. At Meta, managers are expected to move fast, make judgment calls with incomplete information, and correct course quickly when they get something wrong. Interviewers want to see whether you can acknowledge a real mistake without defensiveness, take responsibility instead of blaming the team, and repair the impact on execution, trust, or people.
A strong answer also shows how you handled the human side of the mistake: how you communicated it, how you rebuilt confidence, and what system or behavior you changed so it would not repeat. The best responses are specific about stakes, timeline, and consequences.
Use one concrete example with clear before-and-after details. Strong answers are honest, first-person, and structured in STAR: they explain the mistake plainly, show corrective action quickly, quantify the outcome where possible, and end with a lesson that changed how you manage.
