Step 2: Identifying the text sources

Employee reviews can come from various sources. If your human resources department had the resources, you could have a third party administer focus groups to interview employees both internally and from your competitor.

Forbes and others publish articles about the "best places to work", which may mention Amazon and Google. Another source of information might be anonymous online reviews from websites like Indeed, Glassdoor or CareerBliss.

Here, we'll focus on a collection of anonymous online reviews.
