The phone screen lasts - minutes. You'll get coding problem and - behavioral questions.
You code in a shared editor through Amazon Chime. No autocomplete, no running code. Your interviewer watches you type in real time. Think aloud as you work. They want to see your thought process, not just a final answer.
The behavioral questions target specific Leadership Principles. Expect "Tell me about a time when..." questions even in this technical round. Amazon tests LPs at every stage.
