Amazon has a lot of student opportunities, including internships. If you're a recent graduate, and so interested in a full time position, then checkout the https://www.amazon.jobs/en/teams/jobs-for-grads link.
Amazon is pretty transparent about how it interviews people. These videos are a good overview for SDEs. They are made by actual Amazon employees (the third one is by my colleague, Samir):
I didn't interview as an intern, but I did look up what Glassdoor had to say about the process and it was accurate about what I had to do. So these descriptions about process and questions are probably accurate https://www.glassdoor.com/Interview/Amazon-Intern-Interview-Questions-EI_IE6036.0,6_KO7,13.htm
Right now, we are only interviewing and working remotely (until at least June 2021).
Good luck!
