Circle head is middle mgmt. Doesn't have much weightage. He can give RG , diners privilege.
GH is senior mgmt, much higher post. Once GH gives approval cc team HAS to give. what happens is cc (variant and cl) is approved by underwriter which are low level employee. They reject 1st time around. Then BM has to resend attaching GH approval . At that moment they have to approve.
By doing this, if the customer defaults, underwriter takes no responsibility. If GH has given approval means, in other ways they have already made more money debt exposure. So no one is bothered.
Pricing approval is given by product team. Again once GH gives approval, they don't stall.
