yellow.ai Software Development Engineer SDE interview questions

The interview was scheduled for only 45 minutes. In that interview, introduction + 1 CS Fundamental question in depth(Normalization) + 1 medium leetcode SQL Question + 1 medium DSA Question (Both approaches- Brute Force + Optimized with Code). And after that interviewer told me that I've good skills but he wanted to ask one more DSA Question. I mean what the hell, in 45 minutes what do you want from the person ? And you want full explanation of each thing, and if that's the case then you should describe the process of the interview at the start of the interview, right ? but anyways it was a medium round according to me, but things are not clear and the interviewer is very noob.
