I completed the introductory interview via video on my home computer. They listed several questions, and the company gives you two attempts for each question. No questions were too surprising.
I applied in-person. The process took 2 days. I interviewed at GROWMARK (Sumner, IA) in Jan 2015
Interview
Several questions were asked, experience, background, why I wanted the job, etc. Interview took almost an hour. I was interview by hiring manager, district person, and ego would be the direct supervisor. After interviewing five people they interviewed two internal applicants and picked one of those.
