I applied through other source. The process took 4 weeks. I interviewed at Ocado Group (Weybridge, England) in Feb 2017
Interview
You have to complete a series of online test for verbal reasoning and a maths test which is very difficult unless you have an A level in maths. Then you have an assessment day, one-half is a group exercise (testing your management style) the second half is a face to face interview.
Interview questions [1]
Question 1
Tell me a time when you had to deal with confrontation and how did you resolve it.
