Infosys Systtems Engineer interview questions

my interviewer was specifically tough compared to others , tough luck . it lasted for 15-20 min . thats it i did lots of mistake it being my first interview but tough luck is what i will say

Asked one management level question and one also asked to explain my project.Firstly he asked to give introduction but did not ask for my CV.Then he asked some questions related to my project.Interviewer was friendly and chill.
