WDC has won awards for diversity, but in my opinion they're not deserved. The all-white development/management wing is out of touch with their low income tenants. I heard disparaging comments about the South Side neighborhood that WDC is located in and serves. Also surprisingly gossipy for a small office. My whole time there I felt like I was walking on eggshells. I agree that there can be a lot of useless busywork.
My experience was with WDC, but HOC is probably a better place to work.
