Dow came to my university and held approx. 40 minute 1:1 interviews, which consisted first of a brief presentation of my research. I found my interviewer to be friendly and not especially probing on this first interview. He mostly had questions about my research, then gave me the gist of an information session I had missed the day before. He followed up a few days later by phone. A second phone conversation came a week later with another recruiter. Again, he wasn't that probing and gave more information about the company and worked with me on where within Dow I would be a good fit. Two weeks later, I flew out for the on-site interview. After breakfast at the hotel with my host, I went over to the lab at core R&D and gave a presentation of my research, which was well received. The rest of the visit consisted of a lab and facilities tour, lunch and several 1:1 interviews with employees at various levels, as well as the manager. These mostly went very well with a couple of exceptions. The interview with the program director made me the most nervous. I caught myself elaborating too much. I left with a good feeling overall but an offer never came and my email inquiries were not returned. In truth, it was my first ever on-site interview and initially I was mostly along for the ride as I wasn't in any immediate need for a job. About halfway through, I got more serious about working there but I guess the first impression I gave wasn't strong.
