Avantages
I have seen they pay you more than the prevailing rates in your locality. Because most of their clients are from top advertising countries like USA and UK. So you if they are paying you, or contracted you at 4% commission then you are going to get around one thousand dollar for a single projects. Other then this if you are working their full time then you have a fixed salary apart from a regular bonus basis on the size of a marketing project. You will also be rewarded as the manger is the client provides a positive or five-star review for your services rendered to them.
Inconvénients
But, their prioritization of customer satisfaction more, stressing out the employees for better reviews for their work is a thing that I don't like. The project of marketing should be judged on the quality of the work not merely on the customer satisfaction.
