SAP Data Scientist Senior Developer interview questions

I was called by HR and told to submit resume via sap job site, and got a telephone interview after one week. Two interviewers called me and asked my experience, simple coding test, basic questions about java, data structure, OOP, machine learning etc. It felt like a oral exam in university.I didnt remember some java features mentioned in the question as I use Python most of the time. I got rejected afterwards. The overall interview process is very nice and fast. Although it's mentioned deep learning in their job post, they just asked one concept question about machine learning. I feel like they are more like looking for a senior java developer with some machine learning background.
