  Hilda asteroids orbit at the outer edge, or just outside of the Main Belt,
occupying the 2:3 mean motion resonance with Jupiter. It is known that the
group shows a mixed taxonomy that suggests the mixed origin of Hilda members,
having migrated to the current orbit both from the outer Main Belt and from the
Trojans swarms. But there are still few observations for comparative studies
that help in understanding the Hilda group in deeper details. We identified 125
individual light curves of Hilda asteroids observed by the K2 mission. We found
that despite of the mixed taxonomies, the Hilda group highly resembles to the
Trojans in the distribution of rotation periods and amplitudes, and even the LR
group (mostly C and X-type) Hildas follow this rule. Contrary to the Main Belt,
Hilda group lacks the very fast rotators. The ratio of extremely slow rotators
(P>100 h) is a surprising 18%, which is unique in the Solar System. The
occurrence rate of asteroids with multiple periods (4%) and asteroids with
three maxima in the light curves (5%) can be signs of high rate of binarity,
which we can estimate as 25% within the Hilda group.
