For the people who have jobs

I have question, did you guys get a job through intership or just get it directly by the company interview? I mean just going to intership isn't gonna do anything, I need to know what exactly you should do when you get a intership like to become a programmer in IT , like what do I need to do besides just doing whatever they tell me? Do I need to make connections or smth, I really don't know, I don't see these types of questions. So I am making one. Tell do tell thy secrets for a noob like me.
