Although this is a personal question that only you can answer, we can still provide an example of a possible answer.
A judgement call is a decision that is made without having much knowledge of a particular situation, or without basing it on the available evidence and information that we have at a particular moment.
An example of such a judgement call that I made in the past was hiring the best employee I have ever had. When I was a manager at a store, I was responsible for interviewing potential employees. At some point, I interviewed a young man who had no previous experience in a store of this kind. However, I could see that he was enthusiastic, kind, eager to learn and positive. These were all qualities that I considered important in an employee. Therefore, I hired him without looking at his past experience, and he came to be excellent at his job.
I had considered other people with more experience as alternatives. However, none of them had the enthusiasm and desire to learn as this man. The decision-making process I followed was that of listening to this man speak, and paying attention not only to his words, but also to the tone, attitude and body language he presented. All of these factors convinced me of hiring him, even if I did not have enough concrete evidence to make such a choice.
