While thanking your interviewer is a must, don't bother them with a phone call. Simply send an email or a hand-written note thanking them for the opportunity to interview and that you're looking forward to hearing from them again.
This one is tricky. While you want to make your future employer clear about your salary expectations, you don't want to be the one to initiate the conversation. Wait for them to bring it up and make sure you have good reasons for your asking salary.
More than likely, you're not going to get the first job for which you interview. In fact, the average job search takes eight months. A lot of work needs to go into tailoring your resume for specific jobs, writing great cover letters and prepping for each interview.
Chances are, someone will ask to see your resume at your interview. Either they lost their copy, never got one or stepped in to interview you at the last minute. It doesn't matter – just be prepared with at least 2 – 3 extra copies.
