"Tell me about a time you missed an important deadline. What was the context, why did the miss happen, and how did you handle it with your team and stakeholders afterward? If helpful, you can use an example from a launch on Facebook, Instagram, WhatsApp, Messenger, or another product you worked on."
This question tests ownership under pressure. At Meta, deadlines often connect to cross-functional launches, executive visibility, partner dependencies, and user trust, so interviewers want to understand whether you surface risk early, make trade-offs clearly, and handle bad news directly rather than defensively.
It also reveals how you prioritize when plans break, how you communicate with engineering, design, data science, legal, and leadership, and whether you learn from execution misses. Missing a deadline is not automatically a negative; failing to manage the miss responsibly is.
A strong answer uses one specific example with real stakes, explains your role in the miss without hiding behind the team, and shows the concrete actions you took once you realized the timeline would slip. The best responses quantify the impact, describe how you reset scope or sequencing, and end with a clear lesson about how you changed your operating approach afterward.
