Accenture Sr Software Engineer interview questions

Process is going on for last two months :) . Worst experience I ever had in an interview process. 1- One telephonic round. The person didn't call me on the scheduled day. Next day he called me when I am in the middle of some work saying he forgot to call me yesterday . Still I gave the interview. It was a poor jsp servlet interview. looks like they don't have any work on new techs. 2- After this nightmare they told me to submit the documents. I did that boring lengthy process of submitting n number of docs. 3- No response after that for few weeks. 4- They again called me to submit the docs,I said I already did that but they said they haven't received any. I submitted the docs again. no response after that. 5- This infinite loop is going on for last 3 months. :) They are highly unprofessional and irritating.
