Headquartered in Mountain View, Calif., LinkedIn is a professional network where users can connect with colleagues, network, find jobs, list jobs and further their careers. Basically, where you would share pictures of your pets and kids on Facebook, you'll share your resume and work experience on LinkedIn.
LinkedIn earned a 4.4 rating on Glassdoor and 88 percent of those who reviewed the company say they would recommend the company to a friend. The CEO, Jeff Weiner, also has a high approval rating at 97 percent. Some of the most mentioned perks are similar to other sites, including a strong 401k plan, generous maternity and paternity leave, commuter reimbursement programs and free lunch and snacks.
