Amazon Data Scientist interview questions

Interviewed with a senior analytics manager for a data scientist role at Amazon. Interview was a 1 hour phone interview with a 15 minute SQL test to do on the spot. Interview questions were typical questions about CV and competency based questions according to their leadership principles which went really well and the interviewer kept repeating 'excellent' but the 15 min SQL test didn't go well- despite straightforward questions, I've never understood the point in testing coding skills in a time limit. Received an automated email a couple hours later that I was not successful in moving to the final round and that it was against their policy to provide feedback. I guess its true what they say about Amazon- 0 consideration for applicants or employees. You spend an hour of your time interviewing and do a coding test to not receive any feedback.- v disappointing.
