Networking Sessions - flex or no flex?

Networking sessions...would LOVE to hear thoughts on this. We are all hungry sales savages and want to make as much money as possible. The key to finding that next great gig is networking, they said! In these sessions, what’s the best approach? Keep it conversational and try to build a champion informally? Come prepared with a CV and showcase some wins in efforts to impress? How humble and how confident should we be?

Appreciate any thoughts on what’s working!
