Samsung R&d

First of all the OA had 70MCQs based on ML, DL, NLP, mainly focusing on AI side. Also it had two prompt engineering question. The shortlist was based on OA performance. In the interview, I was first asked about a simple DSA problem. The interview was online, held in MS Teams. I was supposed to tell the approach. The question was to find the maximum possible contiguous subarray sum (basically Kadane's Algorithm), I answered it, and then the interviewer asked some cross questions on that. Next he went to ask about my projects where I told that I had implemented RAG. So, he asked to tell how it works and all. Interview was supposed to last in 30 minutes which happened.
