General

if u get the job can u get me in too thanks

dress nicely, be confident, talk clearly, eye contact, smile, etc. Idk what type of questions they ask but prepare for some generic ones like
- tell me about yourself
- what are your strengths and weaknesses
- what are some times where you had to work in a team and were there any conflicts? how did you resolve those conflicts?

Tell them what they want to hear.

Don't say you hate donuts

Dress casual
Don't stutter when talking/Stay calm when talking
"Why should we hire you out of everyone else?" Be prepared to answer that as well. (Got asked this 4 times in different job interviews of course).
They are looking for someone with communication (at least from my experience).
Stay on topic.
All I can say man.
