It really depends on how one uses a prep. Don't use canned answers. Use the examples from your previous jobs to support what you're telling them about yourself.

The interview itself is a nonevent. It's a very low threat environment, and aside from LOI exercise, there's nothing remotely stressful about it. But there's a lot riding on it, try a multi-million dollar career. Rocky makes it a point to say they can hire each and every interviewee that day or they can not hire anyone that day. It's really down to an individual - no quotas. So, if you received the invite, the job is yours to lose.
