Interesting science, poor communication for small startup - Anonymous employee Flagship Pioneering Employee Review

Pros

- Science is often really cool, lots of smart people - Perks of a big company at a tiny startup (snacks/free food, internal Flagship resources). Better runway than at many companies of similar size due to the Flagship ecosystem. - Good pay and benefits

Cons

- FL company employees are second-class citizens compared to Flagship associates/employees. Communication is gatekept between Flagship leadership and Flagship associates. Dissatisfied with communication and growth opportunities as a mid-career employee - Sometimes apparent lack of drug discovery experience in early FL companies

Pros

A tremendous place to grow and work with collaborative and smart people. You are encouraged to experiment regardless of what team you are on. Pay is also great!

Cons

Some days are tough, we move fast, but that's better than staying complacent.

Pros

Really good summer fellowship, learned a lot. Nice benefits (free meals, activities etc)

Cons

Expected to work really hard. Most days at least 12-14 hours. Given the illusion of scientific freedom but then pigeon holed back into more narrow focus.
