The interview process first involved a Codility test which was quite manageable for somebody with intermediate programming ability. The next step was a 30 minute meeting with the hiring manager. The technical questions being asked where reasonable however, I felt that I was penalised heavily for not having used the Ocado platform. This was the case, when asked a scenario-based technical question, as the interviewer assumed that you knew the platform well and knew exactly what features were available to you to answer the question. In general, I felt that the hiring manager had a very ineffective approach to trying to understand my data science knowledge and applicable skills for the role.
