I was contacted via Linked in for an invitation only recruiting event. They are looking for network engineers. After giving some preliminary information I was set up for a technical phone screen. I was told it it would be a technically in-depth interview. The interviewer called me right on time and reviewed with me who he was and why he was calling. He started out with 3 very standard interview questions like "tell me about a time when you had a difficult issue and how you worked thru it". After these standard question the technical interview started. I was asked 5 to 7 questions that seemed to be taken straight from a CCNA or CCNP exam. For example one of the questions was "explain how a MAC address forwarding table works. I asked how other interviews have been and he told me he wasn't sure how he got picked to interview but he thought it was pretty random that he was picked. So, my interviewer was inexperienced at giving interviews.

Phone interview conducted via zoom. Focused on competency and alot of questions regarding Amazon's leadership principles. Only an internship role so may differ to grad role interviews. Make sure you have strong networking fundamentals.
