Pros
The work was incredibly interesting and the clients were pretty glamorous. A lot of consultancies work on industries such as pharma, healthcare, and financial services, which Vermeer does as well, but Vermeer has a wider range of more "fun" and differentiated clients. You can learn a lot if you apply yourself and ask the right questions.
Cons
The office politics are extremely toxic and the favoritism dictates nearly everything. Aggressive behavior is highly valued, and introverted leaders are scolded for not fitting the mold. Leadership is narcissistic and exploitative. Never in my life have I seen leaders act in such aggressive and condescending ways as I did at Vermeer. People are promoted really quickly, which can be great, but also means that people get promoted before they're ready (and it tends to go to their heads). The hours are pretty insane and random requests come at all times. I've never felt so underappreciated. I'd also say that some of the work and "insights" are stretched... As a client, I wouldn't be pleased with the details of the analytics and other processing that went into the deliverables.
