Accenture Custom Software Engineering Specialist interview questions

I had one round of interview and it went pretty well. Though, in general, there are 2 rounds of interview. I got a call after 2 weeks from HR where they told me I was selected for the job role.

The interview process is not transparent , i got call from agency , hence i applied, got call from different HR peoples , not explained about the role or anything , when we call no body is picking call , Only the interviewer was really good and went well. Currently i am working as technical manager , but the job titile is starting level , There is no POC to call and clarify , when we call the help desk it will keep going on more than 30 mints.. Seems like it will be oneway communcation , every time different HR peoples are keep asking us only , nobody is answering our queires like Role , desigination. etc...
