Point to a specific situation that allows you to emphasize the problem-solving process you took, but don't get bogged down with irrelevant details. The interviewer won't care about the minutiae of a previous work project gone awry, but they will want to hear about the process you went through to ultimately make that deadline.

That being said, it's best to think of a scenario where you end up actually meeting the deadline as a result of your problem-solving. And if you missed the deadline, emphasize what you learned from the situation and the strategies you've put in place to make sure you won't miss a deadline with Morningstar. For example, you might speak to your process for breaking big projects into manageable chunks or how you've developed a system for communicating with other team members. Ensure that you take responsibility for missing this deadline; blaming a team member or unfortunate circumstance won't reflect well on you.

Finally, you may choose to bring up your appreciation for the importance of deadlines within an investment research firm like Morningstar. With ever-changing markets and investors who need to know real-time data, you can imagine how important it is for an analyst to stick to deadlines.
