I got the interview with PepsiCo through a career fair at my university. They are a great company with what seems like a desirable culture to work in. They stressed on the ability to move up within the company as well. The interview was not bad but they definitely know exactly what they are looking for and key words. It was all situation based. Every question they asked was "Tell me a story when..." Examples are when you demonstrated leadership, when someone wasn't happy with your work, when you had to solve a problem. It wasn't too stressful but definitely talk the language of the position you're applying for. Good luck!
