Pros

Fellow researchers are intelligent, competent people that are good to worth with. Work-life balance is great, as you will work no more than a strict 8-hour day as a researcher. The building is also nice and has decent amenities.

Cons

Upper management makes it an almost unbearable place to work. They have in mind a "research process" that they insist that all researchers follow to the letter or else, even though in the opinion of nearly every single researcher I spoke with, the research process is at best a burden that is redundant and slows productivity, and at worst is a huge waste of time that focuses more on branding the company to brokers than actual adding data, and only serves to anger most brokers you speak with. The biggest complaint is the obsession with phone calls. There is a huge push to constantly call brokers to ask for additional information, even after brokers have already either provided information by email or have requested we no longer call them. Also, the goals set forth for researchers constantly change, sometimes multiple times within a quarter. Basically, upper management, who have no research experience of their own and have no idea what the position of a researcher is like, think that they should dictate 100% what researchers do on their time (and change their minds several times throughout the quarter), and the result is predictably terrible.

Pros

Sit all day and play with computers in business casual dress.

Cons

Imagine manning an oar in the galley of a Phoenician war ship. Pull to the beat of a drum. Skip a beat and get the whip. No water for the weary. Zero consideration as a living, breathing human being. Your purpose here is to feed data to the computer. Period. Do not ask questions. Do not offer suggestions. Shut up and pull your oar. Rank-and-yank employee metrics are used to perpetuate high turnover, >60% in 2007. Spring cleaning has already started in 2008. Oarsmen falling like flies.

Pros

None. The pay and benefits are above average, but for a reason. To attempt to trap people there to do this meaningless, growthless job.

Cons

Everything. This toxic company refers to its so-called most valuable "Market Research" department as the backbone of the organization. But the reality paints a far darker, much more grim picture. The job/department itself is not "market research" - you sit down for 8 hours a day and pester individuals for the sole sake of meeting nonsensical metrics. The management does what they're told by the higher-ups. They don't actually manage anything. They also sit down all day listening to and grading calls based on a preposterous script to make the "researchers" sound like robots and not actual human beings. It's a culture of fear and terror, every aspect of the job is micromanaged and monitored endlessly, and there is zero autonomy. Feedback, suggestions, and recommendations to improve processes are NEVER given any consideration. Never. There are no opportunities for growth/promotions anymore (not that there really ever were to begin with). No actual career or development skills are gained from this position. And you'll leave every day dreading returning to it day-in and day-out without any personal or professional fulfillment.
