I had a round at accenture about 8 months ago, multiple interviews over a month and a half maybe; and it went first interview with a manager wanted me to go forward, second interview someone who okayed me for tech interview and what position I should be looking at, third interview tech interview said fine now you need to talk to HR head and she will make final determination, HR head said send you info later in day some days later still nothing, about a week later message from HR needed to have another interview with someone, consulting offer came in I figured well this isn't going anywhere took consulting offer.

1 week later the managerial guy called up and said ok everything went through now we can talk about the job I said "sorry, I took a job". He wished me good luck but I'm not sure from his voice if he really meant it.
