I agree with the commentator above that intially Alexion was filled with employees that wanted to get away from big pharma. Once AZ took over, its been a shit storm. I worked at Alexion for 16 years and left on my own in 2021. Best decision I made and I still keep in contact with a few who are left and even they are slowly jumping ship. Not the old Alexion culture, at all. I’m hearing how horrible and disconnected AZ managers are and not surprised. That's the reason why I left, a manager who I knew cared about the culture was leaving and I was not going to stick through the shit storm that was coming.
