Pros
They used to have good free food, now just has snacks. modern and beautiful offices. They also sponsored me from abroad to come work in DC.
Cons
Worked there for over 20 years and got PTSD in return. At age 70, wanted to retire in the next year or two and was hoping to do some sort of sunset plan. Instead, Bloomberg fired me and gave me a 8 hour notice to try to email all my friends, pack up all my things, and say goodbye to my colleagues. They basically used me for 20+ years and then decided they no longer want me and kicked me to the curb. The worst part, I realized my metro card (which refills in the beginning of the month every month) wasnt working that morning. Then when i got to work, i got pulled into HR's office. I was humiliated and couldn't even talk to my family about it. I wish they thought about the human behind the job. Instead of having a good retirement, it left me feelings hopeless and depressed. I ended up leaving the US, and know that my great experience in the US was all squashed because of the way Bloomberg treated me at the end of my career.
