I applied through university. The process took 1+ week. I interviewed at PepsiCo (Tempe, AZ) in Feb 2014
Interview
Applied through college career link. Had one phone interview were they asked about my resume. Was told over the phone that I had passed and they would contact me to schedule an in person interview. The in person was more resume talk with some behavior questions thrown in. You should be able to say why you want to work there. That was the final stage and I'm currently awaiting a response.
Interview questions [1]
Question 1
What was the most satisfying part of your last job? Nothing difficult, they mostly want to know how your experience is relevant to the position. Less behavioral, more talk about experiences on your resume.
