Pros
You'll go through a tremendous amount of professional anguish due to inept leadership (VP Level and up), product that does not work/yield a positive return on investment for customers and horrible communication. It's a PRO because you'll develop a thick skin and when you actually work at a company that has it together, issues that arise will seem like little bumps in the road.
Cons
I will not spend more than 5 minutes writing a review about CareerBuilder. It is an insult to my and your intelligence to repeat what all of the negative reviews have already stated (they are all accurate and true). I have sat in meetings where management legitimately asked employees to write positive reviews on this site because of how truthful and honest the negative ones have been.
