The slabs should be "perfect" from the shop. This includes sink cutouts. For whatever reason, there is a tendency for faucet holes to be cut onsite. This bothers me, but it's true.

Not only is it stupidly messy, it's less precise, dangerous, and often the crews are too careless to protect the inside of the cabinet boxes (where the slug of stone that's being cut from the top will drop and bounce around).
