So I applied for a summer internship (i'm a HS senior) and got a call from the employer as sort of a pre-screen thing. Should I sent an e-mail follow up just reiterating how much the job means to me and that any further contact is welcome? Keep in mind this is a hs internship kinda thing, not a professional job-type thing. Would such a follow up be seen as initiative and desirable in an employee, or would the employer just think I'm desperate and naggy?
