Infosys Sr Software Engineer interview questions

An HR scheduled first round interview. Then cancelled it. Another HR send me a mail to send some documents at 6pm and asked send that by EOD!! I was unable to take print out. Another HR send me interview request again. I attended the interview. I felt that it went well. After 2 days they send a regret mail. What I felt: The interview questions were not upto the mark and didnt cover up anything. 2 interviewers were there and only 1 was asking atleast an average level question. The other one didnt ask anything good. Interview was for asp.net MVC & Angular, but not a single question was there from angular. And from MVC they didnt even ask the core concepts. I wonder, how they judged me! What kind of magic is that!! Pathetic.
