I have given my interview with Infosys 24/11/218. I am so happy to attend the interview with Infosys beacuse I interviewed with a interviewer who is not from Bigdata background. Unfortunately I am from Bigdata background. Interviewer asked me a question " What is the difference between display () and show() methods in spark sql". I said there is no display () in spark sql. Unfortunately display () is not there in spark sql and your interviewer doesn't know and said yes it is there. Please check with all your Bigdata professional Whether it is there or not? He doesn't know what is hdfs,Mapreduce,Pig and all. Even interviewer doesn't know what is Oracle. What is need of conducting interviews, asking to fill all the forms and making us to wait for 4 hours. I am writing this review because I attened the interview with Infosys year back. That time the interviewer was from AngularJS background unfortunately I was from Java. But he is genuine so that he said as I don't know java so that I am promoting you to other rounds. This time he is not genuine so he rejected me. Please don't conduct interviews like this
