Eaton interview questions

Applied in Jan 2020 and received email about 6-8 weeks later that the position was closed. I looked at the website and saw it was posted again so I applied again. About 24 hours later I received a text message that asked if I had qualifications like have I worked with coatings, do I have BS in Engineering, etc. The engineering text only asked about mechanical or industrial engineering even though the position advertised for a chemical engineer. About 2-3 weeks after that I received an unscheduled call/impromptu phone interview at 5pm from the hiring manager. Received no other correspondence except rejection with no feedback about a month later.
