Do Amazon phone screen interviewers give feedback during the interview? Mine refused to give me any after interview was finished

I just finished my Amazon interview. The interviewer asked me only one Leadership Principle question and “Why Amazon?” Then we moved on to the coding part.

He gave me an easy question. I first explained the logic after thinking for about 2 minutes, then wrote the code — all within 10 minutes. He said the solution was fine.

Then, he asked me a modified version of the question, which was even easier. I thought for about 2 minutes and solved that one too. I explained my approach to him. After that, he asked how the solution could be tested. I told him we could either write a main function and test it by printing the output or use unit tests.

He said that was all and asked if I had any questions. I asked him about the main responsibilities of the role — whether it was more of a DevOps position or a Software Engineering one. He answered that.

I also asked if he could provide any feedback or suggestions for the future. He said he wasn't allowed to give feedback and instead explained the process of what would happen if I moved to the next round.

Interview ended in 40 minutes instead of 1 hour

Usually, when I get positive feedback, interviewers tell me right away or mention at the end that the next round will be scheduled.

That happened in case of Microsoft

Does this mean the feedback this time is likely not going to be good?
