Amazon Applied Scientist II interview questions

I had 1 phone interview doing a medium leetcode problem. After this I did a virtual onsite interview. This took about 7 hours from start to end. I had to give a job talk on my research and had several rounds of 1-on-1 interviews.

I had a mixed feeling after the interview itself that they wont pass me to next. I only had a phone screening, where HR said to only prepare for Leetcode/coding, but the interviewer was all over the projects I did, ML/DL, probability related easy coding question, but nothing related to data structure or algos, so doing leetcode 150 was also like a waste. The interveiwer was very specific about the partoicular word he wish to hear and nothing like other factors which can effect the final outcome of model. I asked him to share the screen and show my paper to explain it better, but he refused to share screen saying that in this part we usually dont allow candidated to share screen.
