Pros
I had a fantastic boss and many wonderful colleagues whose insights were incomparable. The company is well respected. The pay and benefits were great. I learned a lot about the telecom and media industries as well as office politics.
Kontras
Informa is notorious for its ongoing rounds of layoffs. They hire great people and then routinely let them go for no apparent reason other than that fact that they must not have won that quarter's popularity contest. There is a core group of analysts who dominate all initiatives and come up with some really silly projects that waste everyone's time and the company's money. It's sad really, because there are so many better, and more lucrative, projects that analysts could spend their time doing. Further, the culture is very male-dominated, and I ended up being prevented from doing my job as an analyst because the men on the sales team included male colleagues on client visits but absolutely refused to take me along. There were a couple of female sales people who were willing to collaborate with me, but they also left the company. There really are no options for promotions or raises once you are in, and, in fact, the bonus I was promised for completing my first year there was never fully paid.
