Digitas is an incredible organization comprised of some of the smartest and most talented people in the industry. The clients, the people, the work... all incredible and I'm grateful for my time there.
Minpunten
Politics can sometimes get in the way of growth, but that is pretty common in the industry. The only other watch out is for folks that are considering exploring other capabilities/crafts, they may not be as receptive to that as they lead on.
Like most hold co's - its all dependent on your team, but the people on my team are genuinely kind and smart folks. Plus its Publicis owned, so business is actively being won
Minpunten
Classic agency stuff, overworked with many 50+ hour weeks. Publicis' current model is to understaff instead of layoff, so basically every team could use another person. Client has a ton of issues which is not on Digitas at all but does impact the experience.
