I applied online. The process took 2 weeks. I interviewed at PepsiCo (Federal Way, WA) in Jul 2012
Interview
Pretty standard interview consisting of selling the company, the district and the local manager pretty heavily. There were a few questions about sales but, because I am overweight, the interviewer began to focus on how "Hard" the work was and that when "I worked the truck, I was in pretty good shape and it was still a workout for me". It was pretty obvious that they weren't interested in anyone that is overweight.
I applied through college or university. The process took 2 days. I interviewed at PepsiCo (Piscataway, NJ) in Feb 2010
Interview
Interviewed first rounds on campus. It was a very exploratory interview. I was invited back to the HQ for second rounds. You are interviewed by four different people. Two interviews are behavioral, one interview is a resume presentation, and the last interview is a situation analysis.
