What would you decide that?

I would decide that by first gathering all relevant information, then evaluating the options against the criteria set by the problem. I would consider constraints such as time, resources, and business impact. I would also think about trade‑offs: for example, choosing a simpler solution that meets the core requirement versus a more complex one that offers additional features. Once I have a clear picture of the pros and cons, I would make a decision that aligns with the interviewer's expectations and the overall goal of the task. If uncertainty remains, I would communicate my reasoning and ask for clarification or feedback.
