My organization just hired a load of fresh grads. I work with 3 that have started in the past 6 months. Although I get that they want to show what they know, they keep explaining very basic things to me. For example, today, one of them tried to explain how to make a matlab function. I have worked in a matlab environment everyday for +10 years.

I was trying to give him a task and he responded by explaining how to do it like he thought I needed help understanding what to do. When I told him I wanted him to do it, he said no and that it was my responsibility to do it. I was told by our lead to give him things.

He is the 3rd college hire to act this way. Any suggestions on how to respond to them?
