Echoing: don’t come in with a chip OR that we are “lucky to have you.” Better to say you work hard but know you have a lot to learn and are eager to do so.
Things not mentioned: Make sure your physical appearance is up to snuff. Appropriately dressed, hair cut, deodorant.
Use good manners.
And I hate a crummy handshake. As a woman lots of men do some weird floppy handshakes. I don’t know if they do the same to other guys but yuck.
