I applied online. The process took 4 weeks. I interviewed at Waitrose (London, England) in Nov 2015
Interview
Long, arduous and ultimately fruitless. Consisted of basic questions on the application form, followed by several psychometric tests, followed by a video interview (where I failed) after which I'm assuming are more stages before a job offer.

Prepare for everything.
