Interviews

I feel like people interviewing asks questions to set you up. You may think you have a great answer, but it can also be taken as a bad thing...So, what are some general answers we can use and re-word for questions like -What's something you haven't finished? Also, I'm good at eye contact and being friendly-but what other body language is important and telling? What are some things we can include in what we say to show that we really are interested and wanting of the job?
