Pros
Organized environment with processes in place for the most part. Good office benefits.
Cons
Really depends on your team and the accounts you're on. Low pay and little room for promotions. You basically have to be comfortable with the salary you start out with. The New York office isn't that social, even though there are events. Most people just keep to themselves. Just an average corporate environment.
In the last few years, I've seen a lot of change after the most recent CEO was hired. They're regressing their benefits (less time for parental leave, no summer fridays, hammering down on timesheets and time off). Not really coming off as "people first" imo.
As a PM, there aren't many opportunities for promotions. They openly say to all jobs that you only get promotions if there's an opening, NOT if you've worked for it. They're also increasing the number of jobs that are outsourced in Bangalore, clearly trying to save a buck.
