Meta Data Science interview questions

This is probably one of the worst experience of my life in interviewing for a data scientist position. The recruiter reached out me and asked me to study a laborious list of Python, R, SQL, hive, statistics and probability. The recruiter scheduled the phone interview which they constantly kept rescheduling, very unprofessional ofcourse! The interviewer arrived on to call and started with the word "kool" and asked me to open the coderblock. He didn't even care to ask what my name was. He rushed on to the first interview question and asked me a probability question and i gave the answer within a minute. Pat came the reply! Wrong answer! (Even though it was 100% right answer). The interviewer kept pushing me that my answer was incorrect. And he started suggesting me to proceed in his own way and he consumed almost 25 minutes on this. Then he asked me a basic SQL question which he tried to complicate it by not providing the list of values in the table and just complicating that it is tough question. He kept changing his stance on how a record looks and what is the unique key. Then he asked me do you have any questions. He tried to act "kool" as if he has invented the world. I asked him what tools do you use? He kept saying we use hive, python etc and tried to act like he was "uber" cool. I would strongly recommend not to go forward with the recruiting process as you will probably waste your valuable time.

Applied online, which takes more than two month that a recruiter contact me. After contacting me, everything moves very fast. My recruiter set up the phone call in two days, and one day after the phone interview, I got the updates that I can have an onsite interview. Five onsite interviews, one is really horrible. The interviewer did not respect the interviewee, maybe I was not answering the question correctly. But he should not only focus on his computer and seemed that he did not want to talk. Later I asked a question which should be very basic question, he just simply answer:"this is internal question, I do not want to answer." God, horrible experience.
