I applied through campus recruiting and interviewed with a local Dow engineer. I was interviewed for an engineering role in TX but it was filled by someone more immediate. HR was really easy to work with and held onto my application. I was invited to interview for different production engineering positions at a hiring expo in LA. Travel/hotel/food all paid for. Overall, interview questions were mostly behavioral and not too difficult (i.e. tell me a time when...). They even ask you beforehand to present your answer in the STAR format. During the break between interviews, a few engineers asked some basic technical questions related to chemical engineering. I was asked to rank the roles I interviewed for, and in the end I received an offer for my top choice.
