SUMMARY

Covalent bonds exhibit directionality due to the overlap of atomic orbitals, which allows for constructive interference in specific orientations. While s-orbitals possess spherical symmetry, they still create directional bonds as they point from one atom to another. In molecular hydrogen, the bond manifests an oval shape, characterized by a symmetrical longitudinal axis and a transversal plane. This directional nature is consistent across all non-ionic diatomic bonds, even those involving s-orbitals.

covalent diectional??

Covalent bond is directional because it is due to the orbital overlap and orbitals can overlap only in certain directions to give constructive interference. (This is true I hope! comments pls!) .
My question is when two s-orbitals (from two atoms) overlap how can it be directional because s-orbitals have spherical symmetries and have no certain directions??

Well of course it's still directional. It points from one atom to the other one.
 
I'm agree. In molecular hydrogen, bond has an oval shape. It is possible to distinguish a symmetrical longitudinal axis and a transversal plan. Both of them include the origin of symmetry. You can also recognize it in all other non-ionic biatomical bonds, involving even now s-orbitals.
