Pros
Working at MeasuringU gave me unparalleled experience and education in the UX field. You are surrounded by leaders in the space who love to share their knowledge. The speed and variety of the client work makes the days always interesting. Its fast paced and evolving in the best ways. As a small agency you wear many hats, which gives you first hand experience in almost all research methodologies. My career would be no where near where it is today without the learning I acquired at MeasuringU.I was able to work on accounts and projects as a young researcher that I never could have thought of.
Cons
You have to be willing to learn fast and be an information seeker. Though a semi-con for starting out, it will make you a better employee and you will retain the information faster. As with any company, you have to be a team player. Nothing is beneath a job title, its how you get all the great experience though.
