Based on our research and conversations with the instructors/hiring managers at FAANG+ companies, the system design round is not part of the interview process for data science roles such as business data scientist or product data scientist. In certain roles like applied scientist and research scientist, you may be required to have an understanding of the system design. If you plan to target a role like a machine learning engineer, in that case, system design is an integral part of the interview process, and for that, you can look out for our machine learning program.
