RE: Getting a job
I may be young, I know, but I could give a few pointers for interviews, as I've learned a lot in school...
When you go for an interview, like Kirk said, dress appropriately, look sharp, make yourself fancy. When you go in for the interview, you need to be aware of what the boss wants you to do, Don't immdedietly take a seat if not neccessary, wait for him/her to tell you to take a seat, and before shaking his/her hand when entering, try and see if that person wants you to do that, otherwise, wait for them to reach out their hand first.
Small things like this are what people pay close attention to, as well as your body langugage. Look sharp, look calm, know what you're doing and one important thing, don't smoke...
Tada.
