Amazon System Engineer interview questions

Difficult technical interviews . Found out after first round of interviews that the location I was interviewing for is no longer hosting that position and I’d have to go to another state for that position .

Received an email stating I have been selected for an interview and to choose time slots. Then received another email confirming the time and date. The email informed me to research Amazons Leadership principles and STAR interview technique. But none of that had any impact on the actual interview. I received instructions to login to Amazons chime(zoom) at the time of the interview. And that I would be required to take a coding test.
