Amazon Data Scientist interview questions

It started with a phone screen with technical questions and behavioral questions. Then a full day onsite with 5 interviews, covering both technical and behavioral questions as well. Good response time.

recruiter reached out to me, scheduled for tech screen was told it would pure machine learning concept, no coding. actual interview (surprise !!!!!) recruiter mail scheduled the first screen ( then interviewed didn't showed up)- suppose to be pure ML round. last moment change a day before with new interviewer and coding round. WTF!!!!!!
