Answer 1

Go to their websites and see what the age is.  Some places it is 16 but may be younger.

As for interviews, yes, develop a good, firm handshake but nothing excessive.  Direct eye contact and good posture are important.

Dress conservatively and nicely.  Wear nice shoes.  

Practice in front of a mirror but not excessively.  Be yourself and be as calm as possible.
