<human>: Can you condense the text into a few key points?

I recently applied for a member services position with my local public radio affiliate. I'm really excited for the job because 1) I love public radio and am excited to get involved with it and 2) my previous experience ties in very well with what they're looking for.

So I'm not the best at following up on an application. A few times it's seemed to be detrimental; I call and reach the HR office, and they tell me that they'll call me if they're interested, always with an annoyed, inconvenienced tone.

A friend of mine told me I should actually come to the office and check in. This sounds dubious to me. I can kind of understand it, though; when I apply for restaurant jobs I drop by and meet the manager so they know what I'm like and can match a face/personality to the dull resume facts. But that's a restaurant; it's a horse of a different color.
<bot>: When it comes to an office job, what's the most effective way to follow up without pestering the staff?
