LinkedIn is a popular resource for networking, but the company also supplies job listings and, if you're already active on the site, it offers an easy way to quickly apply to jobs. Your LinkedIn profile is essentially your digital resume, and some companies allow you to apply with just the click of a button. LinkedIn offers two apps, one for the networking aspect, and a separate job search app so you can focus on applying, rather than the social side of its service. The app lets you filter by location, distance, company, industry and experience, which makes it easy to find the right fit. It also indicates which jobs let you apply directly with your LinkedIn profile, saving you a few steps in the process.
