MSD Jr Analytics Engineer interview questions

The interview was supposed to be for 50 mins but was done in 15 mins. The interviewer asked few questions and went onto technical discussion. Since I had little experience on the specific tech stack he was asking for (AWS Glue) I was trying to explain him about the pipeline I built in Databricks which is somewhat similar. But he replied "Hey buddy, let's not waste my time and yours, tell me specifically about aws glue". I tried to answer, but I believe he was not satisfied and replied I have nothing anymore to ask you anymore. Weirdly after few weeks recruiter called me to ask if I attended the interview, because she was missing the feedback for me in her system and wanted to schedule it if in case I did not attend the interview. I really don't know understand what's happening behind the scenes, I don't think they are really assessing the candidates as per merit.
