Knowing the answer to the questions above will help you craft a better cover letter, tailor your resume, perform better in the interview and give you some questions to ask the employer. So when you're ready to start your research into prospective employers, these sites are a great place to start.
Glassdoor bills itself as a "free jobs and career community that offers the world an inside look at jobs and companies." Unlike LinkedIn and Monster, Glassdoor is all about user-submitted feedback, or as they call it "employee-generated" content.
Glassdoor also offers information about salaries (provided anonymously) as well as likely interview questions and more. At this point, it has more than three million salaries and reviews posted, providing you with a multitude of valuable resources.
One other unique aspect of Glassdoor is that it finds any connections to companies you search for through the searcher's friends on Facebook. By providing such a connection, it hopes to be able to provide you with enough information to help you decide if the company is going to work for you--or if not, provide you with a personal contact with whom you can get the information.
Indeed.com bills itself as "the #1 job site worldwide, with over 100 million unique visitors per month." Job data on the site comes from more than 50 countries and is available in 26 languages. Indeed has job listings for prospective employees as well as resume listings from prospective employees (you can submit your own resume as well).
Like Glassdoor, Indeed has thousands of company reviews that are submitted from current and past employees. Most company listings have more than 20 reviews, while some-- such as the listing for the U.S. Air Force-- have over a thousand. Unlike the other sites in this article, Indeed is actually a job aggregator-that is, the job listings come from practically every job site out there. Reviews, however, are actually hosted on Indeed.com.
LinkedIn has jumped into the careers market with both feet offering LinkedIn Premium for job hunters and talent services for employers. LinkedIn is well-known throughout the IT industry, and it provides members with a company search feature that provides prospective employees with information about each company that is searched. However, it doesn't provide user-based company reviews like Glassdoor or Indeed. It does, however, provide members with the capability to search for companies based on various criteria, including company size, employment opportunities, location, industry and where it fits in the Fortune 500.
