Does the transfer of energy take place when you push a huge rock

Yes, energy transfer does take place, but is unnoticeable.

While pushing the rock with all your might, you are lifting it off by say mm or μm, and since the mass of the rock is huge it certainly gain some PE. But since you give up, and move aside the mm or μm lift is restrored.

The PE is transferred to the earth particles.
