Amazon Data Engineer I interview questions

4 rounds of interviews after screening round over email. All the 4 rounds were done a single day where we had a multiple people invited for interview and had an interview panel similar to hiring day ( full day interviews for the panel )

I got contacted by a recruiter who explained the process, team, potential compensation, etc. I had a phone screen later that week with a few easy SQL questions. I was then passed off to another recruiter to talk about the full loop. The full loop was all behavioral until the last one, which was another SQL interview by a BIE. The first interviewer asked a bunch about paralellism which I didn't have experience in. Most people were friendly but it was fairly repetitive. I got a call back saying they liked me for Amazon but they filled that position with someone else. They asked if I wanted to do an accelerated process with a different group and I said yes. Then I never heard from either of the original recruiters again. Since then I've been pinged by 4 different recruiters who have also ghosted me as soon as I reply. There seems to be no internal communication whatsoever.
