Maybe it's Rhode Island? But we ask these questions:

What's the difference between clustered & non-clustered index

What's the difference between blocks and deadlocks

What kind of recovery models does a database have (and we'll give hints on this one)

What kind of backups are available (and yes, we'll give hints on this one too)

What's the difference between UNION & UNION ALL

Assuming they pass these, in the phone interview was how they go about performance tuning an unknown situation on a server, and what they know about query hints.

That's it. Most of this information hasn't changed radically since SQL Server 6.5, so anyone with any degree of real experience should be able to answer the stuff... I've got sheets & sheets of interviews with wrong answers on most of those questions.
