We experimentally study electron transport between two superconducting indium leads, coupled to the WTe2 crystal surface. WTe2 is characterized by presence of Fermi arc surface states, as a predicted type-II Weyl semimetal candidate. We demonstrate Josephson current in unprecedentedly long 5 µm In–WTe2–In junctions, which is confirmed by IV curves evolution with temperature and magnetic field. The Josephson current is mostly carried by the topological surface states, which we demonstrate in a double-slit superconducting quantum interference device geometry, realized by coupling the opposite WTe2 crystal surfaces.
