Why interviewers ask this
Most meaningful decisions at work happen before all the data is in, and interviewers want to know whether you freeze waiting for certainty or move forward with a reasoned bet. This question is common for management, operations, and senior individual contributor roles where waiting for perfect information has a real cost. It also shows whether you can articulate your reasoning clearly enough that others would trust the call even if it turned out wrong.
How to structure a strong answer
Describe the decision and specifically what information was missing or unreliable at the time, this shows you understood the real uncertainty rather than glossing over it. Explain the reasoning you used to fill the gap, such as relying on the most relevant past precedent, getting a quick read from the person closest to the situation, or setting a decision deadline and choosing the option with the lower downside if wrong. Finish with the outcome and, if relevant, what you would have done differently with better information.
Example answer
During a product launch, our primary shipping carrier had a system outage the morning we were due to send confirmation emails with tracking numbers to about 3,000 customers, and we could not confirm whether packages had actually left the warehouse. I had two options: hold all the emails until the carrier's system came back, which could take hours or days, or send the emails with a note that tracking might be delayed. I checked with our warehouse lead, who confirmed verbally that the physical packages had shipped even though the tracking system was down, so I decided to send the emails with a brief explanation about the temporary tracking delay rather than leaving customers wondering if their order had even been processed. The carrier's system came back three hours later and every package matched what we had told customers, and we got noticeably fewer support tickets than a previous launch where we had stayed silent during a similar delay.
Common mistakes to avoid
Do not choose a story where you simply guessed with no real reasoning process, interviewers can tell the difference between a calculated judgment call and a coin flip. Avoid stories where waiting would clearly have been the better choice and you rushed unnecessarily. Also make sure to mention what you did to reduce the risk of being wrong, not just that you decided quickly.
