Lutron Electronics Manufacturing Engineering interview questions

I talked to 3 or 4 interviewers. They were all very serious. They asked behavioral and technical questions. The behavioral questions were fairly easy but the technical questions were confusing because they would change the problem situation so frequently. Sometimes I would say the right thing and then a few lines later they would say it as if I hadn't come up with the solution. I became very frustrated and quickly realized this was not a company I wanted to work at. I left after lunch and did not get an offer.
