I have it (CCRN) and never mentioned it during my interview(never really came up), although I sent thank you letters and signed "RN, BSN, CCRN"

The real kicker was when I got the acceptence letter before they got my thank you cards



So in the end did it help me???? I think I answered their clinical question 10x better because of it and I got like a grand from my employer for it.
