Deloitte Senior Software Engineer interview questions

I have given 2 rounds of interviews. In the second round -the manager took the interview, and he joined the call 15 mins late even though I have answered all the technical questions he rejected me for silly reasons.

Interview Process was good and interviewer was professional. One should be theoretically good to crack the interview. Only knowing coding won't help. Overall experience of interview was good. I was interviewed for senior software engineer.
