Pros

I worked for Symbioscience as a summer associate and had a great experience. I had a challenging but rewarding project and amazing exposure to senior leadership at Mars. I may not have enough context to speak to whether this is a good place to work long term, but after looking at reviews on glassdoor want to caution that the negative perspectives look to be written by the same person.

Cons

Some ambiguity in terms of expected deliverables

Pros

Great people who believe in a common mission. Strong leadership and support.

Cons

Budgets and decision making for technical programs are centralized at a high level with little to no consideration for how it affects individual programs and their unique needs. Heavy bureaucracy involved in setting up simple things.
