Getting The Interview

I posted this in the OB forum but I'm moving it here in hopes for more responses! ?

Hi guys! I posted previously about whether I should shoot for a job in Med/Surg or an OB clinic with my end goal being L&D after I finish my RN (I will graduate LPN school in 19 days! Woo!). Happy to report I pursued and was offered a Med/Surg job which I accepted! I am supposed to start late July/early August.

HOWEVER...

A hospital south of me has posted multiple openings for LPNs on their Mom/Baby unit. I have applied for the two full time positions. The hospital is about 4.5 hours from where I live currently, so I would be moving to take this job. I am nervous they will not take my applications seriously because I am applying from so far away. I wrote specific cover letters for each position and included in them that I am excited about the possibility of relocation. Is there anything else I should do in that regard?

I do not want to be that annoying person who calls every day, but in my professional experience outside of nursing persistence was key. Is there anything else I can do to secure an interview? I really want to work in Mom/Baby. I LOVED the patient education aspect of this specialty in my clinical and simulation experiences, and I love that L&D and Mom/Baby are both what I feel are "nurse-driven" specialties and I really want to get my foot in the door.
