Pros
It's a nice place to work.. meaning that the office is cool and well furnished. There are few guys really passionate about their job.
Cons
The business model isn't clear: they're trying to combine the skills of an adv agency and a consultancy firm. At the end of the day they are an unstructured consultancy firm with low (in quality and quantity) execution abilities. The workload is totally inefficient, it is quite common to work during nights, without any extra. There wasn't a very clear personal development roadmap and very low career opportunities. Despite their apparently flat organizational structure, it's quite hard for employees to get listened to: top management doesn't listen to them and they aren't transparent nor clear at all about income, reward and objectives. More than 10 people (1/3rd) left during last year mainly for uneffective management and total absence of reward for employees (not just from an economical point of view: I'm talking about recognition too). Professionally speaking, it was the biggest dream I ever had. It was.
