The interview was friendly and it seemed like he wanted to help me but I didn't prepare for the questions he asked because they weren't in the job description. The first two sections were about data engineering and the last section was about AI.
Interview questions [1]
Question 1
Regarding data engineering, he asked me some questions regarding data integrity and maintaining data quality. He then asked me about ETL and the tools you use for ETL, which I didn't know how to answer. Then he asked about the difference between SQL and NoSQL. For the AI section, he asked some questions about AI and recommendation systems.
