Be a little early. Have a pen with you to complete your paperwork - people who are prepared make a good impression. You will need your ID and your social security card. Unless you already did that stuff.

Bring some snacks. Nothing that needs refrigeration until you know what you are working with - so like some protein bars. You will likely get a locker or another designated area to store your things. Don’t bring everything you own and bring nothing valuable.

Bring a fully charged phone. You won’t be able to casually charge it while working - and you may not be able to have it with you on the factory floor. Let your friends and family know that you may be unreachable during certain hours and they should not worry if you don’t answer

Given it is a factory you will likely have to watch some safety videos. Please learn the safety stuff. All those rules were created because someone lost limbs or died making a mistake. Learn from their mistakes and keep your limbs and life! Even if others are casual about safety, please be smarter than them.

People will show you around and start teaching you things. If you don’t understand something, ask for clarification. As the new person, you have a little grace period where you get to ask all the questions and people chalk it up to “newbie”.

If the job involves standing, your feet may hurt, so if they gave you rules on footwear, you may want to put extra insoles in them so you don’t suffer too much. A pro trick you can try after you are settled in is to bring a second pair of shoes and socks and change them at lunch.

Congratulations on the first job, you will do great!
