AECOM Environmental Scientist interview questions

I talked to a recruiter at a university career fair - I was later e-mailed for an interview the next day. The first interview was to see if I was qualified to work in any of the departments of URS. The second interview was over the phone and lasted around 25-30 minutes. It went well and I was invited to a full day interview about a month later. My interview is coming up this week, so I haven't quite finished the interviewing process! However, I've been told that I will have to give a 20 minute presentation, as well as meet with about 5-6 people throughout the day.

One phone interview with the admin person, then an in office interview with multiple employees and managers.
