If you have one interview and would like to quickly generate more, simply become a name dropper. Mention the name of the company you are interviewing with as you are attempting to set up additional interviews. Most employers have a strong herd instinct that guides them in deciding who to interview. "Oh, you're interviewing with XYZ? Let me see what I can work into my schedule." It's amazing how quickly the schedule will open up for someone who is already being interviewed, especially if the interview is with a competitor.
So when you get an interview lined up, do not single-thread that process through to completion before pursuing others. You are in the very best position to set up multiple interviews immediately after the first is set up. Make the most of this opportunity.
