Accenture Senior Software Engineer interview questions

The first interview was to be face to face ,they called me to Accenture office and I gave the interview over call! The second interview round happened many weeks later, abruptly without any schedule while I was out. Then I got the offer pretty fast. On reaching office at joining date, i was told my HR wasn't reachable and I'll be given another offer letter with another date!!!!!! Had to fight over mails and got a date further 4-5 days late. I switched cities for this! Not a good experience.
