  We present a time- and angular-resolved photoemission (TR-ARPES) study of the
transition- metal dichalcogenide WTe2, a candidate type II Weyl semimetal
exhibiting extremely large magne- toresistence. Using femtosecond light pulses,
we characterize the unoccupied states of the electron pockets above the Fermi
level. We track the relaxation dynamics of photoexcited electrons along the
unoccupied band structure and into a bulk hole pocket. Following the ultrafast
carrier relaxation, we report remarkably similar decay dynamics for electrons
and holes. Our results corroborate the hypothesis that carrier compensation is
a key factor in the exceptional magnetotransport properties of WTe2.
