I applied through college or university. The process took 1 day. I interviewed at Dow (East Lansing, MI) in Oct 2014
Interview
General campus interview. There was no specific job description. The resume was submitted to the recruiters through the department secretary. An one on one interview was arranged for each applicants (I believe all the applicants got the chance for the interview).
Interview was ok. Gave 45 min presentation with approx 10 attendees and had personal interviews with approx 5 people. Don't remember much else unfortunately as this was a while ago.
I applied online. The process took 5 weeks. I interviewed at Dow
Interview
Long but very useful. Met several stakeholders who gave a good overview of the process. At PhD level, you will have to present your work. Got a tour of the facility

On-site interview with multiple interviewers asking specific questions based on my resume and work related experience. Some behavioral type interview questions related to how I work with others and how I handle certain difficult situations
