Oracle Data Scientist interview questions

Although it was a screening interview, the interviewer really delved into technical questions and I wasn't able to answer the questions that well. Then the interviewer said that he is looking for a technical scientist person for this position and that I don't seem like a good fit.

First round is questions about your background, followed by a case study. At the end, they ask a few technical questions that are fairly straight forward. They also spend a decent amount of time talking about the position.
