Swiggy internship but via Comett Staffing?

Someone I know got a internship offer from Swiggy but the offer letter has come from Comett Staffing. Upon speaking with the Swiggy team they shared that we hire interns via staffing agencies.

This is in the marketing team. Has anybody else heard of this? Is this something to be worried about?

Interviews were done by legit Swiggy employees (email ids were also @swiggy.in)
