I interviewed at Ocado Technology (Hatfield, East of England, England)
Interview
You apply online, then they give you an online coding assessment which was quite easy, and then they give you an online behavioural assessment. They then have a 3 hour virtual assessment centre where there is a group task in the beginning and then technical interview with some of the engineers.
