We recommend making reviewing and contacting applicants part of your daily routine while you are actively recruiting. When you are passively recruiting, set aside time at least once or twice per week to review and contact applicants. For step-by-step information on reviewing your applicants and contacting them to begin the recruiting process, click here: How do I move my applicants through the hiring process?
To contact applicants faster than your competitors, consider enabling text messaging on your account. (More info: Using Text Messaging)
