Pros
Technology driven company with exciting projects. Very stable and easily makes revenue targets because of lack of competition. Has a very good reputation amongst the Science and Engineering world because almost all students use MATLAB as undergrads.
Cons
The only way you can survive at this company is by becoming a cog in the wheel. There is only one way to do things and that is The MathWorks way. Creativity and new ideas are discouraged, unless they come from employees that have been there forever. There is no such thing as ideas adopted from the outside. Quality of first and second line managers is extremely low. Most have never seen any proper training as managers. Extremely paternalistic senior management. One of the worse places to work is Technical Marketing. There is no leadership from the marketing organization. Product direction is totally dictated by development. Technical Marketing is side stepped by sales, AEs and customers. Best way to describe their role is as "checklist marketing" ; just execute what is on the checklist. It doesn't matter if the material is used by anyone. In general it is not. If Technical Marketing disappeared tomorrow, no one would notice.
