Follow up after 7 business days?  That seems like an awfully long time after the job applicant's initial correspondence with cover letter and resume, no?  As a hiring manager, are you really that put off by anyone that makes an attempt to follow up with you sooner than 7 business days?  To some degree, I feel like I want to show the hiring manager that I care about the job opportunity, I am proactive, and that I am reliable.  Am I crazy for thinking a follow up in the 3-5 day range after initial application is ideal?
