Pros

Excellent colleagues, company values, vision, mission and science. Company aims to be patient centric, and they are.

Cons

Management. Limited prioritization with a range of efficiency projects that have people running in circles with no work-life balance and a required 4 days in the office (vs. most biotech companies at 3 days).
