Amazon Intern (Operations) interview questions

Online interview via HireVue. I had to answer approximately 5-6 questions. Afterwards, I ha two calls with Operation Managers at fulfillment center. They asked me about obstacles I had to take during my career as well as basic interview questions.

The interview was friendly. However, the interview questions weren't standard for all. For some it was easy and others, questions ranged in to technical topics even though it was explicitly mentioned that we would be asked only about our projects and other stuff based on our resume.
