Niagara Bottling Project Engineer interview questions

I was asked a number of questions regarding details of my resume and other improvement projects I had been associated with in my prior position. Additionally, I was asked to draw out a flow diagram for the current reverse osmosis system in one of the plants I was previously working in. There was no pressure, but more a check of my comprehension while working briefly with the unit. There were also questions about an undergrad project I had worked on that were stressful as they went into more detail that I could either remember, or had been taught during the project.
