Amazon Applied Scientist interview questions

Had a phone screen with a group leader. He was quite awkward and not really well-spoken. He didn't care about brain teasers that he was supposed to ask me and let me do the assignment later and submit it to him. He mostly asked about my resume points and wanted to see if I can come up with ways to use my particular expertise for Amazon. The day after the phone screen I was invited to an on-site, but that invitation was withdrawn due to my visa situation (they couldn't wait for me to get a visa).

Two round back-to-back phone interview, 45 mins each. The first round is general coding. The second round is a computer vision coding problem. The interview process is professional and fast.
