Accenture Application Development Engineer interview questions

Very Unprofessional Behaviour of Accenture HR Team, Literally I waited for 1 hour in the interview lobby and interviewer didn't come and when I tried to call HR she didn't received, atleast she can inform me that due to some reason the interviewer will not join but no they don't have that much courtesy to call and email , according to me HR don't know the value of candidates time.This is my humble request kindly entertain the candidate call and update everything to the candidate.Most funniest part is that in the accenture recruitment process site also written that "We know how important regular updates are. Whether we’re extending an offer or giving you some advice to help with future interviews, we’ll be in touch as soon as we can. "Either remove those line or make sure to work on this. Hope there is some site so that we can share our own feedback to accenture portal. Please consider this feedback.
