What does it mean that we are listening to internships?
I was doing an internship this week, and I got to do a lot of things that other interns weren't allowed to do, like driving a truck. I said I'd like to come back sometime, and they said I did everything very well.
At the end, the boss said to me, "We'll talk." What did he mean by that? Positive or negative?
That sounds positive. He probably wants to talk to you for further training or for employment. You seem to have made a first good impression.
