Pros
Most of all I liked the people around me. The project trainer always explains everything clearly and is friendly, the manager is great, all the consultants in the team are fun. We grew and developed together. I left because 3 years in one job is not typical for me. I took a break and will probably come back, time will tell. I miss people. The job was multi-tasking, new information every day, and it keeps me toned and dynamic.
Cons
Sometimes I got tired of the dynamics, but I needed more rest.
