I've never had my personal values align with a company like I have with SEI.
Pros
Working for a company who values are aligned with your own makes all the difference and that is why I chose SEI as an employer. Almost 4 years later I have no regrets and have never been put in a place where I have had to compromise my values or beliefs. SEI is a growing, fast-paced, results oriented organization and therefore is not perfect, however at the end of the day it is an ethical company who places customer service and their people above all else. It's a relief to be able to tell others about SEI, knowing that we can actually back up and deliver on our promise to prospective customers and employees (which can be rare most places now a days).
Cons
SEI is not a company where most employees can get away with just doing what's in their job description. Because of our growth, employees are often stretched and required to do more for a period of time until we hire or bring in the resources necessary. That's not the best job or environment for many people while some people thrive in it.
