I applied online. The process took 2 months. I interviewed at GSK in Dec 2016
Interview
Multiple stages including online testing, video interview and assessment centre. Video interview was competency based, assessment centre was a mixture of group and individual tasks. The assessment centre was a great experience and even had I not got the position would have been very helpful for my learning
submit application online > online assessment (refresh page after completing it, another test will probably appear. keep doing that until no additional tests appear. they won't email you to notify you that you have outstanding tests and page doesn't auto update) > Online automated video interview
