Amazon Data Scientist interview questions

the initial round was a telephonic call of 45 minutes in which recruiter (Actually he was a technical person) asked about the experience and technical questions as well, basic SQL codes, also one or two leadership principle questions. The second round was a coding challenge there were two questions one SQL question to write a query and the other one was python code. then called me final round which was a 4 consecutive round with 4 different people from 4 different team. the first person asked about leadership principle questions, the second one asked techniacl questions, mostly Algorithms, optimization, and SQL the final one was a coding challenge again, he asked to write a query and also to write a python function I believe I performed well, I wrote all the SQL queries and python scripts but they asked me if I can find the solution to python problems in any other ways, like, without using certain libraries And I said I can but maybe I need a few more minutes but they allowed 15 minuted to each question
