I applied online. The process took 2 months. I interviewed at GSK (Sydney) in Nov 2017
Interview
Online application followed by video interview and finally an assessment centre (3 minute presentation, personality and interaction game, and finally an interview with manager). The assessment centre was a whole day process and I received an offer that afternoon (although some may take up to a week)
Interview questions [1]
