How does 2 hunters to 1 guide work ?

I am interested in going on a elk hunt in British Columbia and going with a hunting buddy of mine. I am not sure what to expect with 2-1 Guide hunt. Can some explain how it works? Are booth hunters hunting each day or is it one kills first and then you hope that the other gets a shot later in the hunt?

Any help is greatly appreciated! It is a expensive trip to go on and just not sure what to expect!

Thanks
