Pros
Generous 401(k) match (which you will use to justify staying at Pew long after you've realized how miserable you are). Amazing colleagues (who you will bond with quickly as a result of your shared misery). Great location in Chinatown/Penn Quarter.
Cons
Before I took my job at Pew, I read the Glassdoor reviews over and over. "It can't possibly be that bad," I told myself. "There's no way." I quickly realized that I was dead wrong. I am therefore here to tell you that "IT IS ALL TRUE" and worse than you can possibly imagine. Pew is the most toxic, demoralizing place I have ever worked. Don't let the "prestige" of the Pew name fool you. RUN, DON'T WALK, in the other direction. Trust the countless others on Glassdoor who have explained the serious issues in this organization. I will leave you with one last thought -- The average length of tenure at this organization is LESS than one year. As you consider your job offer, ask yourself why that might be.
