Quick call with the hiring manager, a take home on a real data set. Then another interview with some of the team and a final interview with some more senior people.
I applied online. I interviewed at Ocado Group (London, England)
Interview
Started with an one hour video technical interview. One simple computer science coding question, and some technical questions around modeling, e.g., time series models and modeling ideas in some ocado-specific use cases.
Then an on-site interview. This covered a tour in the ocado wearhouse, a technical interview, lunch and a culture fit interview. The technical one is a live coding interview to analyze some data.
The whole process went smoothly. The HR were very helpful and friendly. I have the impression that the team in general is very knowledgeable about computer science/engineering, less so about modeling, which is not necessary a bad thing. However, based on the questions asked during the culture fit interview and the feedback I got, I highly question the integrity of the leadership team, which is a really bad thing. I would continue shopping with them, but won't apply a role from them.
