Cons
Mathematica is one of the most unscrupulous companies out there. They will not uphold promises to anyone—whether you're an employee, a customer, or a business partner. They always find ways to wriggle out of employment agreements, contracts, or any commitments that no longer serve them. As an employee, if a senior executive makes you a promise—even in writing—don't count on it sticking. Once that exec is gone or things shift, someone else will simply tell you they won't honor it. Do not work for this company. Do not do business with them. Save yourself the headache and look elsewhere—there are better options out there that actually value integrity and keep their word.
