At 40+ mph speeds and drive over a bump in the road the rear feels like jello... on 2009 Hyundai Santa Fe

I have brand new tires and just changed the rear shocks.
Mechanic states everything looks OK ... but I when I drive at highway speeds and hit a bump the rear bounces like jello.
I hit a series of bumps I have to slow down

it sounds like you have a suspension problem to check it try to bounce the rear of the car if it bounces more than once then you have a problem be sure you have new shocks or are they struts?
