Amazon Business Intelligence Engineer interview questions

A recruiter reached out to me to see if I was interested in the position. On three occasions, the interviewers didn't show up. They would not tell me the reason. Very unprofessional! On the fourth occasion, the interview held.

I had 3 rounds of interview: 1. Phone Interview - Technical - 4 SQL and 4 Python 2. Phone Interview - Behavioral Interview with hiring manager - based on leadership principles 3. Virtual Onsite Round - 1 technical round (3 SQL, 4 Python and few questions on visualization and ETL) and the 4 behavioral rounds based on leadership principles . Be prepared to have at least 2 examples for each LP because some questions are repeated and they want us to provide different example for each case. Also tell them realistic examples because they will deep dive into solutions and you should be able to answer all technicalities and logistics.
