Amazon Software Graduate Development Engineer interview questions

I had a first phone screen, which was an hour long, had 15 minutes of Hr questions based on Leadership Principles, then 45 minutes of real-time coding problems, You need to know a bit much about DSA to be able to pass the coding challenges, you must think out loud.

The first interview was a technical one that lasted 30 minutes. Interviewer was friendly and helpful and focused on the technical questions. The interview was not too formal which helped with the nerves
