" Post Interview Don’t forget to send a written “Thank You” card to each interviewer (no e-mails unless it is in addition to a written one with additional info like a personal thank you video). This is especially important between multiple rounds of interviews; take the opportunity to show new information demonstrating you are a subject matter expert (article, video, portfolio, etc.) after each round of interviews. And follow up minimally by phone to show continued interest without coming off as desperate or a stalker. "
