Usually they will find a relatively quiet place to talk to you. Generally, not many people will interview together, but they will interview alone.
According to my personal experience in HR, a resume doesn't need to be flashy, just express your manager, education and contact information.
Remember that KFC attaches great importance to team spirit, so you should pay more attention when asking similar questions.
Other things to pay attention to are how long you will work in an organization, whether your people have affinity, and remember to smile when interviewing.
If there is anything you don't understand, you can ask me.
Remember to give me extra points for the last important thing, haha!
