Basic questions—it all depends on the points you discuss. For example, I talked about my graduation project and the technologies I used, so they asked some questions about these technologies and how they work. They also asked some basic data science questions. The core of the questions focused on the 'Why?' aspect, such as 'Why did you use this technique?' and 'Why this specific technology?'
