    hybridisation in carbon compounds is easy...

    If the carbon has four single bonds it's using sp3 hybridisation
    If it has one double bond it's using sp2
    If it has one triple bond it's sp
    If it has two double bonds (unusual) it's sp

    So C=O bond would be the overlap of SP2+sp2 unhybridised orbitals?

    from the pont of view of the carbon:

    it forms three bonds so it's sp2

    from the pont of view of the oxygen:

    It's using a p orbital to form a pi bond with the carbon (after forming a sigma) so it also is sp2

    BUT your statement lacks clarity.

    The single C-O bond is overlap of two sp2 hybridised orbitals, but the pi C=O component is the lateral overlap of two parallel (unhybridised) 'p' orbitals
