Facebook on-site sounds so different...

I have an upcoming onsite at Facebook and in the email there is a part which says I will get to meet different team-members and live a day in life of the team I am interviewing. This is a new grad role. This sounds very different from other on-sites I had including Google where I was put in a room(s) and just asked to solve coding problems by different engineers without meeting any team members. Just curious if Facebook will end up doing the same or will it actually be more interactive with the actual team? I honestly have no idea what to expect. Does anyone have experience with Facebook on-site?
