DXC Technology Service Delivery Consultant/Associate Professional interview questions

As I applied through cocubes that is why I started my interview process from the second step i.e the technical followed by an HR round. There are basically three rounds 1st is pre-assessment conducted by co-cubes and technical & HR. My interview took minimum 40 minutes as she asked so many questions from java as it is my base subject after that asked from DBMS and as I am from ECE she asked about my ece projects like Arduino asked to draw gates truth tables etc but she was quite in nature and gave enough time to answer. Basically, prepare a subject very good rest were the very silly and common questions. I saw many people were rejected from the hr round as because their dress code and communication skills, be cooperative there and try to be in a formal dress, questions were just intro what technologies you know etc just formalities.
