Answer: An unsolicited application letter
Explanation: Debbie being a job seeker with desire for employment with a particular organisation that has not posted open job requisitions, in this case, an unsolicited application letter is used as an inquiry about possible openings and to gain a hiring managers attention. Contacting employers with an unsolicited application letter can open doors that were previously closed to you. The unsolicited application letter acts as an introduction to you, your skills, and why you're a good fit for that company.
