I applied online. The process took 7 months. I interviewed at BAT (London, England) in Jan 2016
Interview
The process was fairly long, with little to no communication about what was happening (or not happening), esp. as the person in charge of testing was not based in the London office and her contact details were difficult to obtain.
Interview questions [1]
Question 1
Can you influence senior people? (the organisation is highly hierarchical)
