I agree. If you can put plenty of force on the lever without it bottoming out and the brake pads have no friction, the pads are contaminated.
Considering that the work was done by a shop, I'd take it back to them and have them replace the pads. New pads shouldn't be contaminated out of the box. It sounds like they may have dripped brake fluid on them.
