Part 3 of Sears interview in a week! What is a culture conversation?

I was put through the second part of a three part interview system that this sears uses... Apparently, its one of the top sears, not only in the district, but in the region as well.... So expectations are high.

But, this associate told me that I am scheduled for part three with the store manager, who has the final say in whether or not I get hired.

They said that I was scheduled for a "Culture Conversation"... I don't know what happens, or what to expect during that sort of thing.... What is it about, and what should I expect?
