Final answer:
Applicant tracking systems risk missing out on a large talent pool without mobile access, as many job seekers use mobile devices to submit applications.
Step-by-step explanation:
Applicant tracking systems (ATS) can miss out on a large talent pool today if they lack the functionality of mobile access. As we transition further into a digital age, the need for mobile-friendly online applications is paramount. A significant number of job seekers rely on their mobile devices to search for jobs and submit applications, making it crucial for ATS to support this type of access. Without mobile access, companies risk overlooking qualified candidates who may prefer or need to use mobile devices for job applications due to convenience or lack of alternative resources.
