Nagarro Senior Nodejs Developer interview questions

One of the worst interview experience I ever had. First you need to qualify 3 rounds of test which I did to reach to the technical interview. First is Aptitude test 30 questions in 20 minutes (I don't know why they take it seems the treat everyone as fresher) Second coding round in which you need to pass all test cases Third mcq 100 questions in 100 minutes spread accross 5 sections 20 questions per section If you clear all these 3 rounds they will call for the interview The interview was organised for 30 mins. The interviewer seemed completely uninterested in the interview. Without any intro he just started. Asked one MySql question which was answered. No mongodb question. Two questions from Javascript in which 2 was answered completely correct and one was partially (It was disadvantages of Hashmap in which I told one) And 3 questions from node which were also 100% correct. Still I was not selected. No got any feedback from the interviewer what was wrong. One more thing he asked whether I had worked on Stored Procedure to which I said no. His words were to exact, that So have you just written select statement. My point is please don't waste time of the candidates if your interviewer is not interested. And how in the world could you judge any person in 10 mins that too based on 2-3 theoretical questions. When that person has already cleared all the coding rounds.
