Digital Trends – With over 100 million users on the LinkedIn service, itâs clear that potential employers can find tech-savvy candidates through the site. LinkedIn is making the process easier with the launch of the âApply with LinkedInâ button for employer sites. A company takes a few lines of code, drops them into the job posting and applicants can quickly submit applications for the position. Companies can also customize the button to require a cover letter or answer a series of questions to qualify for the job.
