Pros
Mindshare is an open workplace, where staff is empowered to make decision and to share their points of view. A great peer-to-peer training. Majority of colleagues are open to sharing. If I don't know something, I can talk it over with anyone whom I believe helps me solve it. Mindshare also provides exclusive internal training in media planning and client service. The most interesting part of this is graduation pitch, in which you work in a group to make a communication proposal to real-life clients in only 3 days. Lots of pressure and overnight work will give you memorable experiences in return.
Cons
Slow career progress to entry level, particularly interns. you must work hard significantly, handle beyond-scope-of-work tasks, in order to stand out from your peers and junior executives and to get promoted to senior staff. Low pay in Mindshare, compapred to other competitive agencies. Besides, payment is not transparent, unfair in the same employment position. When getting promoted, you are paid less than someone who is recruited for the same level, given the similar experiences of less. So, in this trapped situation, it's hard to ask for fair adjustment, due to limit in your annual salary growth rate.
