Amazon Software Engineer interview questions

I applied Online and received a Hackerank coding assessment, followed by four technical and behavioral rounds, including system design, with the Hiring Manager. All the rounds went well, and feedback was good but I was not hired.

I got an assessment from Amazon and soon after that I got a mail to schedule final loop interview. The only problem was I didn't knew if it was SDE1 interview or SDE2 interview since I had four rounds.I mailed my recruiters multiple times but no one replied, then I asked a friend who works at amazon to check internally and I found out it's an SDE2 role. I got cold feet since I was preparing for SDE1 based on my level of exp. So during the prep call(part of preparation before interview), I talked with the Host(Speaker) that I feel SDE1 L4 is more suited for me and also how my recruiters are not replying to any of my mails, then she asked if I graduated within last 24 months and I said yes, then she said she will contact my recruiter and will mail her. So, following this, my reccruiter out of the blue just canceled my interview(without even asking me) and told me she will try to schedule a SDE1 interview. And after that she ghosted me. I contacted her several times but she didnt even replied. I know I should have gone with the SDE2 interview, but I thought they might have power to schedule me an New grad SDE1 interview since I graduated in last 12 months. My recruiter had no right canceling my interview without even asking me or scheduling another interview. Worst recruiters and no decency to reply to mail.
