In link state routing protocols, full update that happen every 30 minutes, does the routers exchange the whole routing table with each other? Or exchange something else, not full routing table. If not the whole routing table, what they are exchanged?

The interval depends on the routing table. OSPF will send out a fresh copy of the LSA (link-state advertisement) every 30 minutes. ISIS will send it every 20 minutes. Only LSAs are sent, not the routing table.
