I saw a case just today. Client's DBA role had been outsourced (to a local company). The person responsible for all of their admin is just about straight out of school, got a couple courses and certs under his belt, no experience.

Size of the database - currently 1.2TB expected to grow to 6TB within a year.

Apparently just about every time the DBAs do any work on the system, they bring the whole thing down, and this is a 24x7x365 system.

Fun. Not.

Edit: I should say DBAs because there's more than one involved. All about the same level of wet-behind-the-ears.
