they called me, one on one, two on two, panel, questions, op a RFP to send to a select number of RFI responders. Anything included in your RFI could be utilized in the RFP, giving the competition the chance to get a glimpse of information you might have shared, processes you might use, and advantages you might have over other options. For this reason, you might want to save some of your important differentiators for the RFP portion of the selection process instead of sharing them too early on.
