just like when i started out training at a prominent hotel here in my country, I kept my mouth shut acted I knew nothing and kept what I knew to myself. I just listened to them and asked them what they wanted. each place has their way of doing things. each recipe is different, even their process on doing certain things will vary quite vastly. just say to yourself that you are starting fresh and you are a blank canvass. only when the chef says he trusts you enough with some responsibility and gives you the freedom to do what you wanna do with said responsibility is then you can do what you want with what was given to you. like in culinary school, only thing you need to say for the most part while being in the kitchen is, "yes chef!".The CIA is a great school, congratulations and I hope everything is going very well for you there!
In addition to what other members have already told you, I'd like to just remind you about keeping your mouth firmly closed. I've seen enough guys come in and start talking about their school, how they were taught to do this in such and such a way, etc---no one wants to hear you. We had a guy like that start recently, everyone started calling him Hermione(the girl in Harry Potter), once the dishwashers caught on he didn't last the full week.
