Be prepared for these questions!

After 15 months of the interview process, these 10 questions appeared in almost every job interview I attended. If anyone could post their creative answers to these questions, it would be most helpful and much appreciated.
What are your weaknesses?
Why should we hire you?
Why do you want to work here?
What are your goals?
Why did you leave (Are you leaving) your job?
When were you most satisfied in your job?
What can you do for us that other candidates can’t? What makes you unique?
What are three positive things your last boss would say about you?
What salary are you seeking?
If you were an animal, which one would you want to be?
I would also like any comments on questions that have stumped you in the past.
