Pros

Not much other than decent headquarters, but even that went downhill

Cons

Terrible management, no strategy and then takes it out on the rest of the employees. Miserable place to work! 10-12 years ago, it was a very reputable company that was anticipated to grow rapidly. Now they are a shell of what they were with a failing pipeline and massive turnover.

Pros

Astellas is a truly globalized Pharma with Japanese heritage and offers and uniquely international environment in Japan. The leadership is kind, empathetic, diverse and collaborative. People care deeply about their work and contribution to patients’ lives. There is good momentum with the pipeline, and exciting transformation at the moment. Many long term employees and alumni who return to Astellas mostly due to culture. Excellent work life balance with full remote work flexibility for most employees.

Cons

Can be a bit slow to adapt and evolve compared to US biotechs. Still many processes are in silos and cross functional communication can be poor in some areas of the org.
