Procter & Gamble Internship interview questions

Most questions were asked about my background and experience with a heavy focus on the answer format: problem definition, resources, alternatives, decisions, outcomes. I was supposed to have a panel interview but somehow they could not arrange it so instead I had 3 1:1 interviews, each lasting about an hour. It took them for ever to give me an offer, just a few days before the start of the internship. Moreover, some of my interviewers were extremely sleepy, which made me question their professionalism.
