Pros
It's inspiring to work at a company that is doing such great design work across the globe. Gensler has a vibrant company culture evident the day I interviewed. In San Francisco, the artwork on the walls rotates every 3 months, as well as during the holidays there is a wonderful children's holiday party where volunteers re-imagined the workspace into scenes from Alice & Wonderland this last December. Many employees take part in volunteering in the community. In addition, there are a lot of opportunities for career growth, and I find I have the space at Gensler to take on projects that stretch my skill-sets. If you love being in an environment that is centered around Design Thinking, this is the place to be. Colleagues are professional and helpful, and I've found a good work-life balance here.
Cons
Compensation for non-architects (UX specialists, software engineers, designers) working in firm-wide operations has not kept pace with the bay area salary market. Gensler is also going through the normal growing pains when a company grows in both #of offices & #of employees in a relatively short period of time.
