Amgen Associate interview questions

The interviews were good, I spoke on the phone with the hiring manager and then was invited to come in for a series of four 1:1 interviews. Everyone was very friendly and clearly loved working in the team and at Amgen. The questions weren't purposely difficult (they weren't trying to trick me or test me) but they did want to go in depth and hear me talk in more detail about my resume.

1. Phone screen with recruiter 2. Phone interview with director in the department 3. On site interviews: 4 back to back All interviews were fairly short (30 min) with no tough questions really--only behavioral, talking through your resume & it was very much conversational in that the interviewers spoke a lot about the department and day-to-day responsibilities for the role. I got the sense in the final interview that they weren't really interested in hiring me. Overall, everyone was nice, and the reimbursement was generous. However, I informed them beforehand that I had other offers at hand and would need a decision promptly. They said the position start date was ASAP, so no worries there...until I had to follow up multiple times weeks after the final interview just to get a generic rejection email. I'm absolutely positive that had I not followed up, I would've been kept in silence. This cost me an offer from another company due to their inefficient, slow response--very disrespectful.
