I applied online. I interviewed at Ocado Technology (Hatfield, East of England, England) in Dec 2015
Interview
Was asked to complete an online Codility test, this consisted of 3 programming problems. After completing this I was invited to an assessment day. We had to complete 2 short tests, one was a logic test using a made up assembly style language, the other was filling in the blanks for some code in Java. Following on from this we got a tour of the CFC (warehouse), some talks from members of staff and a free lunch. Those that had failed the tests were sent home, the rest of us had the usual technical interviews consisting of coding problems, general computing knowledge and discussing past experiences.
