I applied through a recruiter. The process took 2 weeks. I interviewed at Ocado Group (London, England) in Jan 2015
Interview
Written test up front. Didn't meet anyone at company really, they just sat me in a corner and told me to write out some code. Seems like they were looking for skills rather than learning potential.
