I don't think that they can skip the interview.
Do realize they are our alter ego and they fly Delta passengers every day. Hiring them is ministerial.
Since we allow multiple standards in our contracts it is common sense that management is eager to advantage themselves to the less costly standard. In the past Delta pilots have insisted on industry leading pay based on the belief that Delta's selection process made us worth it. IMHO the Pinnacle bridge agreement was designed to demonstrate pilots who value their own skills much less than their peers are Delta pilot material.
Nearly every regional airline management is using the Pinnacle Bridge Agreement to justify concessions to remain competitive.
