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.
