So, I applied for a job in mother-baby

I'm really hoping it works out. I submitted my application and resume online and they automatically send you an e-mail saying thanks and they will contact you if they want more info. It seems to me like it was meant to discourage people from calling back. Placing a follow up phone call is so ingrained into me that it feel wrong not to. Would you still place a follow up call? If so, to who - the human resources department/nurse recruiter or straight to the unit manager? What would you say? The last time I placed a follow up call it was kind of lame because I hadn't really planned out what say beyond "I was calling to check on my application status". The nurse recruiter didn't really have much to say except It's still open and we'll call you if want an interview. A little discouraging...
