Pros
Some people from the team in my account were amazing. Great professionals, hard working, kind, smart and creative. Workload is not a lot, slow processes in the client side makes it imposible to move forward anything. Also Nacar offers some really good trainings for their employees.
Kontras
Basically you are a contractor for one of their clients. On Nacar's side, HR team will not support you and would just please the clients. They make the best - for Nacar - out of every situation. You can not trust HR team. On the client´s side, they have only one big client, a big corporate that treats external workers with disrespect, micromanages them, and have zero technical knowledge. You will not learn anything. A second minor client is a pharmaceutical, though people on Nacar working there seemed happier.
