Ventajas
MathWorks is a great company. I started my current role mid-pandemic, and have been very impressed by how efficient and smooth both the interview and onboarding process have been. Management is very supportive and understanding, and people seem to maintain a good work-life balance. Salaries are generally pretty middle of the road relative to other tech firms in the area, but for me this is balanced out by good benefits and reasonable expectations from management. I'm hopeful that they will relax their previously strict work-from-home policy after the pandemic is over.
Desventajas
Onboarding and ramp-up is a little on the slow side. Company has some very strict internal policies and ways of getting things done, that can make projects a little frustrating. Promotions seem pretty rare.
