Phone After Application
It’s fine to call — once. What you don’t want to do is harass them, but one phone call a few days or a week after you submit your application is fine. It might sound something like this: “I submitted my application for your __ position last week, and I just wanted to make sure my materials were received. I also want to reiterate my interest in the position; I think it might be a great match, and I’d love to talk with you about it when you’re ready to begin scheduling interviews.”
