My 2 cents without inside knowledge of this company:
If it's a SSTR followed by a guaranteed P2F of at least 500 hours, it's amoral but may get you over the "real job threshold". Decide for yourself if you want/need to do it.
If it's a SSTR without guaranteed hours, it's amoral and an utter waste of money. A TR without at least 500 hours is of absolutely no use - just check the job ads.
