Pros
I worked at Experient for about five years and had an overall positive experience. The company is certainly a leader in the conference and event industry. I found the company culture to be very respectful and they have good procedures and tools in place to make the work consistent across project teams. Additionally employees were social and often gathered outside the office socially.
Cons
Some of the downsides I found to be a lack of automated reporting and accounting functions which caused frequent requests for manual updates and reporting on which the criteria changed. Additionally, there is not a sharp focus on the specifics of profitability at the project level and while I strived to address this issue it was not possible without the cooperation of other departments who did not comply.
