AstraZeneca Senior Scientist interview questions

I applied online through an employee referral. It took two weeks until I was invited for an initial 30 min screening non-technical phone interview with HR. About a week later I was invited to a 30 minute slightly technical virtual 1-on-1 interview with the hiring manager. About two weeks after the 1-on-1 meeting I was invited for a half day (~4 hours) of virtual 30 minute 1-on-1 meetings with AstraZeneca employees and invited to give a 1 hour presentation. Some interviews were technical and some more values-focused. I received the offer two weeks after the third stage.
