Accenture Sr. Software Engineer interview questions

the first communication was extremely formal and impressive through a ,mail invite etc from the HR IDC of accenture. Later i was scheduled for telephonic interviews for Technical, HR which i cleared. after my HR round i recieved a call for F2F managerial round which was a complete bogus. upon being there 50-60 interviewees were made to wait for hours and then allowed for a final round with any manager with no-connection to the projects i was interviewed for before. the HR over there pathetically explains to people why same managers are interviewing the same persons again and again and that consultancies have access to use accentures official mails ! ... when everything else stopped making sense to me i was called for the "managerial" round which turned out to be 101% technical. i was later given the feedback that i was not shortlisted ?!.. though atleast it was quickly given!.
