Amazon Applied Scientist interview questions

PhD student in computer science here. Background: 100+ citations on my 14 AI/ML research papers. 3 media coverage articles on me I had amazon interview and there were 7 rounds of interviews with 2 initial rounds with Hr and senior data scientist. 2 initial round with HR and then with Senior Data scientist 1 presentation 6 rounds of interview with the team Within those 6 rounds I was asked leetcode question difficulty was hard. I was able to solve the leetcode with no issue. I had great interviews with all and I was expecting an offer letter. Sadly HR called me and said that they have moved with other candidate. Hope they realize that it’s not nice that you put an candidate through several rounds of interview and just throw them out. Never going back to apply

The interview process was ok but I hate so many behavior question / leadership princeples, totally 11 of them on onsite (5 rounds, every rounds have 2 bq and one round has 3)
