Maritz Research is a traditional marketing research provider organized by client industries/sectors.
Pros
Recognized expertise in the area of customer satisfaction tracking research. A quality pool of quantitative data science professionals well-versed in current and emerging analysis options. Overall Maritz Research has a Midwest sensibility that seems to encourages team work and often rewards loyalty.
Cons
Your work experience is highly dependent on the industry/sector team you are with and the tone set by the senior management of that particular group. One sector might be highly collaborative with contributions rewarded regardless of your level, another sector might be quite the opposite. One sector might have a more friendly informal team culture while another sector might be much more rigid and formal. Maritz has tried with limited success to expand uptake of research offerings beyond customer satisfaction trackers. If you are looking for research experience beyond c-sat you may be happier elsewhere. Like many employers they have steadily required employees to kick in more for health insurance which can impact your take-home pay.
