DXC Technology Data Scientist interview questions

I was contacted by a recruiter (Diamondpicks) who had tie up with dxc technologies for the position of Data Scientist and i was shortlisted for an interview on 5th jan 2019 at dxc technology office. The job description and everything else matched my resume perfectly. On reaching the venue i was made to wait for 4hrs exactly before being called in. The interview didn't even last for 30sec. I was interviewed by a person from dxc technology. He straightaway told that they were looking for person with 5 years of experience and i wouldn't fit in. Cooly said that he could have informed it before but he had some other work. Nearly all the 10 people who attend for the same position were humiliated the same way and sent home after waiting for hours. Such a disappointment, if these people are not sure, then why call people and waste their time. Such a worst experience and worst people. Please stay away from this company. They don't even know how to treat people and value talent. He further added that i can't do the work properly quoting my age as the factor, which i strongly disagree. Look for talent not the age.

there will be 2 rounds 1st will be ML based paper which will have 15 questions and 1 hour will be given and 2nd round will be F2F interview
