AECOM Graduate Water Resources Engineer interview questions

I applied online through URS portal. After 1 month they contacted me for a telephone interview with the project manager.I did not have a HR interview. I had a 30 minutes phone call conversation where the questions were mostly technical and team related. I got a call from the HR within one week saying that I was selected for the next round which was a skype call interview with multiple project managers. As the job location was far from the place I lived, they wanted to complete the entire process on phone.They asked me questions for about an hour which were highly technical and a couple of them were related to my managerial skills.
