Ventajas
There are very supportive and professional people working at Northpoint. Working as a consultant is the best thing for a computer programmer, you are open to many different technologies, ideologies, techniques. As a consultant you are never stagnant, you get to learn new languages or new techniques since not all projects are a like, you meet interesting people. Working in different and some pretty amazing companies gives you an opportunity to learn to communicate with different personalities and adapt to all kinds of situations. There is a lot of growth opportunities at Northpoint, since you can start as an Associate and grow all the way to Senior Manager or even Partner. They have a culture of promoting from within as well as teaching their employees by having "lunch and learns" and all other learning opportunities. I do feel like they are my daytime family, we do some fun things together too, so it's not always all about work.
Desventajas
For me personally there are really no cons here. I would agree with other reviewer here that sometimes projects are not 100% estimated but I think that's a normal agile planning issue that exists in any place where planing is not easily achieved.
