You must bring a written resume and you will be asked questions during the interview. The interview company rarely helps you print your online resume. The most important thing is the diploma, and the others are some certificates I took. It's best to copy these certificates yourself, so it's very important to take both the original and the copy. If you have something small, take a pen and paper with you. If you have anything to record, you can always write it down.

In addition, you should be prepared before going, introduce yourself, ask about company benefits and so on.

I hope it helps you. I wish you a successful interview.
