That comes with some pretty big assumptions. Oh, and you pay for it because yes, you do need it.
You assume that the operators minimum requirements in their Company Operations Manual allows for pilots to be hired with a CPL with either a Group 1 or Group 3 Instrument Rating. Almost all [read ALL] will save the hassle and hire only those with CPL and a Group 1 unless they have no other choice. Why would a company agree to hire you knowing you are going to cost more to train than the next guy down the list?
You also assume that you are getting a PPC on your first gig.
Quite a number of operators would only do a PCC for a Right Seat job. Any operator flying an aircraft which is certified for single pilot ops and does not require a type rating (Navajo, Beech 99, certain King Airs, even a B-1900 operating under 704) but who operates as two crew only needs to complete a PCC for the second pilot - not a PPC.
Last but not least you assume that the check pilot is authorized through their ACP to issue initial ratings. Quite a number of ACP holders are only authorized to renew IR's - even if they are expired, not for the issue of initial ratings - which would be required for an upgrade from G3 to G1.
