Why should I hire you?

This is a big question. As you make your presentations remember that the interviewer is thinking that statement. There is more to the process than just your knowledge. You need to be able to communicate and the biggest part is fit with the team. You can have every skill, education that is needed yet if you don't fit the group it isn't going to work very long. Sometimes it may be that you could improve some skills then again on the other hand you will realize that you are just not comfortable. It is a hard decision to turn down a spot that your skills fit but if YOU don't fit you are better off to thank them and move on.
