  This study presents Fermi-arcs mediated transport in a Weyl semimetal thin
slab, interfacing two $s$-wave superconductors. We present detailed study with
both time-reversal and inversion symmetry broken Weyl semimetals under
grounding, orbital magnetic fields, and Zeeman fields. An orbital magnetic
field induces energy level oscillations, while a Zeeman field give rise to the
periodic anomalous oscillations in the Josephson current. These anomalous
oscillations correlate with the separation of Weyl nodes in momentum space,
junction length, and system symmetries. Additionally, we present an explanation
by scattering theory modeling the Fermi-arcs as a network model.
