The company still has the mind set of a small company (< 500, in mid nineties) and has a hard time growing into the culture of a mid size company (>3200 in 2015). Middle-management is very slow in motivating engineers or giving them opportunities for growth. This is mostly because there is no competitors (except for open-source, the biggest enemy of MathWorks).
You get a cozy job with no opportunities for growth. You may work here for a long time and never get promoted because"you're compared against others", a nonsensical alibi given by managers who in most cases are not technical at all!
