2. Asked few SQL questions
few rounds of interviews ranging between technical and conversational. Mostly in the form of " tell a story of time where ..." to show how you relate to amazon LPs
The first interview is a technical phone interview that assesses your skills in SQL and Python, specifically data analysis with python. The interviewer pastes the description of an SQL problem on the code editor and asks you to write your answer while describing your thought process. They give you hints when you're stuck.
