Initially applied through a recruiting agency. The woman at the agency did a phone interview that lasted 20 minutes. She was very friendly and helpful in advising what to expect at my interview. I was told to prepare for a 3 hour interview that would be in 2 weeks. When I arrived at the plant, they did not have my name on the list to enter, so I had to call and wait about 30 minutes for the interviewer to arrange for my entrance into the plant. Once I was in, the lady who was suppose to interview me handed me off to the head chemist and said he would interview me instead. Once in his office, I had about a 30 minute interview, where the chemist told me he had never interviewed anyone before, and made up a bunch of questions to ask me. He did not write my answers down nor have any prepared questions. He then let me know that they were looking for someone with less experience out of fear that I would get bored and leave, and he told me all of the reasons I wouldn't want the job. As he led me out, he said I would not have to meet with anybody else and he would make a decision by the end of the week.

I had a phone screening then an on-site interview. The onsite took well over and hour to complete. They cycled through different lead researchers each with their own questions. Some ranging from typical questions and others asking for more in depth explanation of your knowledge.
