Let's say I work as a bartender, and I want to mention the fact that I worked as a cook a while ago. Do I use the Past Simple or the Present Perfect? For example:
Person A: Do you think you could cook meat?
Person B: Sure! I worked as a cook/I have worked as a cook.
I am aware that when we are talking about the things that are no longer true, we use the Past Simple, as in my the context above. And we use the Present Perfet when we are talking about past experiences up until now, as in my example in my sentence. Working as a cook is an experience, right? I'm confused which one to use in the context I provided and in resumes.
