Pentair Automation Engineer interview questions

Phone interview with talent acquisition manager, phone interview with hiring manager, in person interview with operations manager, HR manager. Excellent feedback at this point, then I was given a technical project to complete in a week and present to a panel. I did not have pricing from vendors and asked for additional time. They wanted me to present without pricing, I questioned the reasoning behind doing that and then the process was ended. I suspect they were just looking for free technical help.
