  Platinum ditelluride has recently been characterized, based on angle-resolved
photoemission spectroscopy data and electronic band structure calculations, as
a possible representative of type-II Dirac semimetals. Here, we report on the
magnetotransport behavior (electrical resistivity, Hall effect) in this
compound, investigated on high-quality single-crystalline specimens. The
magnetoresistance (MR) of PtTe$_2$ is large (over $3000\%$ at $T=1.8$ K in
$B=9$ T) and unsaturated in strong fields in the entire temperature range
studied. The MR isotherms obey a Kohler's type scaling with the exponent $m$ =
1.69, different from the case of ideal electron-hole compensation. In applied
magnetic fields, the resistivity shows a low-temperature plateau,
characteristic of topological semimetals. In strong fields, well-resolved
Shubnikov - de Haas (SdH) oscillations with two principle frequencies were
found, and their analysis yielded charge mobilities of the order of
$10^3\,\rm{cm^2V^{-1}s^{-1}}$ and rather small effective masses of charge
carriers, $0.11m_e$ and $0.21m_e$. However, the extracted Berry phases point to
trivial character of the electronic bands involved in the SdH oscillations. The
Hall effect data corroborated a multi-band character of the electrical
conductivity in PtTe$_2$, with moderate charge compensation.
