I have interviewed for 4 positions already but no offer, I have developed a sense that Amgen Hiring managers/managers just can not recognize talent, or are threatened by one, and that is why overall the company is not developing new drug but rather making the same drug work for different indication.

My job was in therapeutic area. I knew the hiring manager from graduate school. He was collaborating with my phd advisor. He knew that I was looking for a job, and I spoke with him. It all seemed good. I was invited to give a talk. Then a second interview with more people. Then an offer was extended quickly.
