Pros
Mathematica used to be a place where people would go to make their careers. You are surrounded by very smart colleagues who work very hard. In general, it’s a very collegial environment with a strong supervision component help mentor early career staff.
Kontras
Senior leadership is tone deaf. They are unable or unwilling to transparently communicate with the larger staff when making very important decisions that impact the entire company. Leadership is bloated and overpaid. They were utterly unprepared for dealing with the second Trump administration. The company seems to be shifting from its roots in policy research to more of a data analytics consultancy. Thus, the skill set that they value reflect that shift. Several years ago, the company articulated company, wide “values.” However with the recent downturn in policy, research and federal contracting, leadership has turned its back on these values, opting instead to protect the company, no matter the cost. These values ring very hollow now that the market has shifted.
