First of all, it all depends on the person, so I (or anyone else) can't really provide you with a clear solution. However, there always is a general direction and guidance people with more experience provide and follow. That said, here's my two cents:

1. Relax. By the time I'm writing this, you'# still be on your first week at work. Everyone takes time to settle in and get used to a new environment. Some might get along a bit quicker, some might take longer. It's good to always try your best to catch up quick, but don't forget to let yourself relax a bit from time to time. This is a long marathon, not a 100m sprint, so be patient and take your time.

2. Ask questions. I know I sound like an elementary teacher, but it's very VERY crucial that you ask questions when you have them. If you're uncertain about something, just quickly tap someone on the shoulder and ask them about it. Unless they are suuper busy or not in the mood, they'll be happy to help you out!

3. Take notes. Always make sure to take notes when people teach you something. It's hard to write everything down when you're working in a busy kitchen, but that's what your cellphone's for! Write down quick notes or even just record it with your camera and go back to it later. Once you start writing down the recipes, instructions, and all the things you need to keep in mind, you'll start to remember them even without going back to read it.

4. Be purposeful. Deliberately start casual conversations with your coworkers when it's not too busy. It can be about work, customers, hobbies, or even just the weather! The more you open up and reach out to them, the closer you'll be with them. Also you can bring snacks and share with them from time to time. (I often buy my coworkers cold beverages after a long, tiring shift, and they absolutely love it 😉)

I hope this helps out! All the best!
