This is great. I don't think people pay enough attention to employer reputation.
When advising job seekers, I always suggest they look at reputation first. Make a list of companies they admire, ask others for their impression. Just as you use Yelp to find a fish taco, use Glassdoor (not perfect but a good indicator) and -- important -- don't just look at the rating, read the reviews to understand why people liked or disliked a place. Because you need to know if a place matches your style. One person's 4-star is another's 2-star.
