Umm...I don't think my sink is quite ready for a sink full of soapy water and dirty dishes.
With a granite sink (not one that is honed out of an enormous solid piece of granite - nurses don't make that much), you have to do it a step at a time. Today our granite man put all the pieces together like a very heavy 3-D jigsaw puzzle. And measured and made sure it was level and plumb this way and that. And adjusted. And measured again. And again. And, FINALLY, when he deemed it "perfect," he epoxied the bottom of the sink in place. Once it sets up, he'll add more pieces.
