Amazon Embedded Software Engineer interview questions

Phone interview. They didn't asked many working experience. just went over the resume then jumped into coding test. It is tight to do this in such situation. Tried to finished. But some were missed. then no response. It is hard to prepare the coding because you never know what will be asked

The recruiter contacted me and set up a phone interview with the hiring manager. He asked about my background and experience. Question: write a Hex file for Ring Buffer, write code for push and pop functions.
