Pros
There are two things that I miss about Digitas: The generous number of vacation days/paid holidays and the people. When you're inevitably burnt out and beyond frustrated, you'll need both of these to cope.
Cons
Where do I start? 1. The clients - they're big, and with big comes boring and super demanding. 2. The management - I had 3 different VPs and 5 different managers in less than 2 years, and sometimes no manager at all (and this situation was quite common). Promotions are hard enough to come by as is, especially when everyone who is tasked with molding your career walks out the door. Also, senior management will suck the life right out of you if you let them. 3. The priorities - thanks for the tap room and random vendor-sponsored happy hour perks, but how are we supposed to enjoy them when we always have an insurmountable amount of work? 4. The lack of work/life balance - with management as checked out as they are at Digitas, there was no protection between us and internal/client firedrills. 5. The lack of efficiency - my days were full of meetings that could have just been an email or two. Ugh. 6. Speaking of meetings, the multitasking - everyone always had their computers out in meetings and spent the time half multitasking and half listening, which meant that no one ever fully knew what was going on. If it's not important enough to listen to, cancel the meeting. And if it is, put your freaking computer away! 9. The cross-capability teamwork - all of the internal Digitas teams (account management, media planning, strategy & analysis, tech, integrated production, etc.) kind of hate each other. Make friends in other departments whenever possible because they'll save you in tough times and brighten up your days.
