Ventajas
The emotional take on market research is interesting. They give you a laptop, a phone, a lot of vacation, free snacks, and a couple of mandatory team nights out a month. A fair amount of independence - good place for self-starters. If you don't suck at your job, you'll get a title and pay increase every 18-24 months. And with such high turnover, it's fairly easy to rise quickly. They do a good job of dangling carrots to keep junior staff keen. Ability to work from home occasionally.
Desventajas
Very high turnover, so teams are always changing and struggling to keep up. With no actual training process in place, it takes months to get new people up to speed, especially since things are constantly changing in how we do things. The laptop and phone they give you mean you're always working, even when you're not. They never hire enough people to do all the work, so most of us work crazy hours, including nights and weekends. Great place to work if you love corporate burnout though. Lots of senior executives hanging around not helping. Lots of vacation days, but it's always too busy to use them. Management is basically a good old boys network - a lot of overweight white guys. Very little diversity in management or in the workforce. US management especially can be very petty, hypocritical, passive aggressive, and negative. It has created a really negative culture over the past year or so. Their claims of being innovative get old after a while, especially since our survey software is barely functional and everything we do is very traditional. We just use the words "emotion" and "behavioral economics" a lot in our reports. Promotions are pretty routine. If you don't suck, you'll get one every 18-24 months, but the job never changes. It's just a different title and a little more money. Even when you're in a senior position, most of the work you do is still intern level. It's more of a research factory than an agency. Not a good place for someone trying to learn how to do market research. Pay is lower than the industry average, but they try to make up for it in the extra vacation days you can never take.
