I saw an Accenture representative (the HR rep for that state) at a career fair, handed off my resume, references, cover letter, etc - and discussed my experience. Several weeks later, I got my first interview scheduled through my university's career center. From there, the process was pretty straight forward:
1ST INTERVIEW: About 30 minutes long, 1:1 with a senior manager. We discussed my work experience, background, the structure of the company, and interest in Accenture - no behavioral questions. This was "The easy one," as the recruiter said. They gave me plenty of opportunities to ask questions, and here's a key - use those opportunities! They don't like it when candidates just stay quiet (friend of mine didn't ask anything, and he wasn't invited back). That night, I got an email saying I qualified for the second round of interviews.
2ND INTERVIEW: My second interview was held over the phone, because they did not have enough time slots at the university to fit everyone in. No big deal. That friday, I did my second interview over the phone. It was with another senior manager, who was working from home that day. This was a behavioral interview. Mostly team-based questions, like when were you involved in a team, and the result wasn't as good as you wanted, when did you disagree with a co-worker, etc. There was also a question that I found on here, but thought to myself "there's no way I'll get that question." I prepared for it none the less, and good thing! they asked it. It was "tell me a time when you had to debug an issue with a computer system" or something like that. Again, lots of opportunities to ask questions - make use of them. A few days later, I got an e-mail inviting me to the third and final round of interviews.
3RD INTERVIEW: This was an on-site interview. And let me tell you, their new office in downtown Houston is VERY neat. But if you're more into a traditional office - it might not be for you. So make sure you check it out properly before leaving. Anyway, on to the interview. I was there with a group of six or so other candidates. We were there for three hours. The first hour involved an office tour, and a benefits presentation, which also discussed Accenture's corporate citizenship and the like. The next two hours were two 1:1 interviews. The first was all behavioral - but these questions were a bit more technical, more specific to the position. I assume they were trying to figure out if I really knew what the position was, and if I had any experience dealing with high tech systems in the past. Again, time for questions. The second was a bit of the same - but slightly more open, with more "why acenture?" questions. Remember, if you mention travel and projects - they'll probably say "you could do that with any firm - why us?" so come up with something better!
The next business day, I got a call with the offer. It was pretty much spot on with the average for <1 year in Houston listed on this site. They gave me about a week and a half to get back to them, but i'm sure more time was available if i had really needed it.
Keep in mind - when I say "ask questions," i'm talking about questions more pertinent to the position and specifics of the company, such as how they measure success.
