As an extension of professionalism, engagement is a driving factor behind successful interviews and hiring processes as a whole. Being engaged starts when you apply and carries through the entire hiring process—both with hiring managers and your recruiter.
Part of engagement is going through the hiring steps in a timely fashion to show your recruiter that you are truly interested in a position, Ask informed questions during an interview, and following up with the hiring manager and your recruiter afterward to keep yourself top of mind during the process.
The more engaged a candidate is, the better the results—and the more willing and able their recruiter will be to help through the hiring process to a job offer.
