Follow-up can significantly affect whether or not an offer is extended. Following up after an interview addresses a key employer concern: your interest level in the position. In addition, you are demonstrating, by the very act of following up, personal and professional qualities that are typically sought by an employer: dedication, tenacity, attention to detail, and the ability to follow through. In some instances, employers may even use the lack of follow-up as a screening device meaning, it’s a way to narrow down the number of candidates to a short list and those who do follow-up ultimately become finalists.
