For any job seeker, Send out a thank you card to them the same day you had had an interview. IF they say they are interviewing in a week, wait one day after dropping off your resume/job app, then Call. Ask to speak to a manager or HR dept..
Tell them you dropped off a job app/resume and are very interested in working there.
If you get an interview, do the thank you card, and then a day or so after it should have arrived, call to say thank you for the interview, ask how the process is going and again say how much you would like to work there.
Getting your name in their heads, and calling them shows that you are truly interested.
