Final answer:
Using only conventional job-search methods without leveraging social media's potential for networking and job opportunity visibility is the least effective tactic for getting hired as a social media manager.
Step-by-step explanation:
When aiming to get hired for a social media management job, the least likely tactic to succeed would be the sole reliance on conventional job-search methods like solely submitting resumes and cover letters without leveraging social media. In today's job market, especially in fields related to digital and social media, it's essential to recognize the importance of the hidden job market and to employ diverse job search strategies.
Successful job seekers often use social media to their advantage by following influential recruiters and organizations, engaging in networking activities, and promoting a professional online presence. A job search campaign targeting decision-makers via social media can be particularly effective. Conversely, ignoring social media platforms or leaving a negative footprint on your social media accounts can be detrimental, as potential employers often scrutinize an applicant's online presence.
Therefore, the least likely tactic in getting hired would be to disregard the potential of social media sites for job opportunities, fail to network, and leave an unprofessional digital trail.
