Accenture Senior Analyst interview questions

Usually it is a three step interview process, first one is a telephonic round followed by one technical face to face interview and one competency based interview. the entire process took about a month and I was offered the role after 3 weeks. The joining process took one more month after all required documents and references are provided.

I rather experienced a funny interview process. My resume was selected from the Accenture pool. Had two rounds of interviews with the Project Manager and the Program Manager and got selected in both. The only issue they raised during the interview was regarding the Work Visa approval. After a few days, HR emailed me that they are not proceeding, without citing a reason. But after a few days again, the HR emailed me and asked me I am still available for the same role. I said yes and they started the further negotiation. The next day, I received a call from HR's manager for salary discussion and he agreed upon an amount. That was the last time I heard from Accenture. It's been a month after that discussion and HR has stopped replying my emails or receiving my calls. Never expected such a poor C grade interview process from such a renowned company. A few HRs are creating a bad image of the company and the company is not aware of this.
