The first interview was with HR and recruiters. They asked the typical questions like "why PepsiCo" and questions about work experience. They mostly just want to learn about you in the 1st round of interviews. This consisted of 2 interviews, both on the same day, one right after the other. The first interview was 1 on 1. It went well, fairly easy. 2nd interview was 2 on 1. They asked most of the same questions as the first interview but wanted to know what I was hoping to get out of the internship. The final round was behavioral interview, asking questions like "Tell us a time when you solved a technical problem" or "How did you resolve a disagreement". The final round was with two PepsiCo employees and was definitely harder that the 1st round. They wanted clear concise answers.
