I applied through a staffing agency. The process took 4 months. I interviewed at AstraZeneca (Chennai) in Feb 2015
Interview
It took 4 months for end to end processing, with 10' of follow up. Between every interview there will be silence for over a month. then suddenly they will wake up.
Dont depend only on this, keep multiple option open, use this offer as bargain chip outside.
Interview questions [1]
Question 1
Those where simple as they dont have proper panel to interview
