So, I've got a question...

Strong handshake!

Good eye contact.

Yes sir, yes ma'am.

Not many folks dress up for interviews these days, I always advise a dress shirt and tie for the boys/men and something professional for the gals.

No mumbling, speak up, be pleasant and receptive.

Ask them a few questions. "What opportunities for advancement are available?" Ask them if they enjoy working there and what their favorite part of the job is.

Older adults are usually very impressed by younger folks that are polite and engaging.

Work hard and show them you are eager to learn.

If this is job 1, it is your foundation for the future. If you are hired, impress them, and you will have a great reference for future employment.

Good luck!

All of this 100%. I'm a college professor and just served on a job search committee and you'd be surprised the lacking level of professionalism in self presentation, correspondence, etc that I witnessed over the course of this search committee's duties. Downright embarrassing in some cases. A little bit goes a long way in my book. Walk the walk, talk the talk, play the game by the rules/expectations... employers recognize these things.
