Interviewer won't respond to email?

<p>So, I got the email from GT about the local alumni on thurs the 17th and emailed the guy the next day. Its been 3 days and I still havent recieved any reply. Im starting to get worried...idk if I should call the guy or what
And anyone got any tips/insight for the interview?</p>

<p>Definitely call, because it is easier to just glance at an email or delete it. It seems much better if you call to schedule the interview.</p>
