Companies rely on machine learning engineers to help design and improve the systems that allow their software to improve on its own, rather than being specifically programmed. During the interview process, be prepared to be tested heavily on both computer science and data science knowledge with an emphasis on recognizing patterns and trends. A bachelor's degree in computer science or a related field will be required.
Describing my previous experience, ML theory (some of which was fundamental stuff which I struggled to recall, but most of it was straightforward and what you'd expect from an ML theory interview), and walking through a case study with the interviewer (presented with a modelling opportunity, asked what things I would need to consider and walking through the steps to get the ML model over the line).
They are very interested in that besides pure machine learning knowledge you also understand the broader business context (i.e. how and where ML can solve business problems for Deliveroo)
