Clean Water Services interview questions

I had a screening phone interview at first and then was invited to an in-person interview. It was a friendly environment, but questions was difficult. Too much focus on the details of the project that I had done many years ago, and barely could remember their details..

Knew someone working there at the time. They put me in contact with the Operations manager. We went back and forth over a few emails. Then did a phone interview. He mostly asked about my past experience with manual labor. He also stressed this was a physically demanding job (it was indeed). I assured him I was up for it.
