AstraZeneca interview questions

I had a phone screen and was scheduled for a face to face interview with 2 hiring managers within 2 weeks of the phone screen. The hiring manager stated the company was looking to fill the position within a 4 week time period, but after 2 failed attempts to check on my status, I never got word if I was moving forward a month after the interview. Finally, I did receive an email at the end of March stating I was not selected to move forward. However, around mid-April I received a phone call from the hiring manager to come back for a second interview. The second interview last about 30 minutes and again I was told I would be contacted in the next few weeks, to which I never was.
