Ring Software Engineer interview questions

Initial phone call, follow up video code interview, 4 hour in person technical/behavioral mixed interview. Got an email saying they were not moving forward. Negative review because I asked for feedback and they gave me a “amazon won’t let me give feedback”.

Had a phone call with HR for 15 minutes about the role and then technical interview. I got the question right since it was a question a freshman in college can do and even answered follow up questions correctly when asked about scalability of the question, but was still rejected for some reason because I didn't fit with the team. They might have chosen someone with more experience as I have 3 years and they were looking for 3+ years. There were 2 people, 1 from ring who knew about the product and 1 engineer that did the interview. The engineer was kind of strange and sort of untrained. He....talked....like this... in almost a robotic way and didn't ask me anything about myself, my job, my interests , just started the technical portion right away and even tho we ended 10 minutes early did not ask me any questions to get a better feel for me as if I was never a consideration for him personally, but got the interview only because the manager wanted to give a shot. He is originally from Amazon and has the same 3 years of experience as me. I dont think the interview process in Amazon is good but HR portion of Ring was replaced to align with the Amazon recruiting process because I had this same exact problem for one section of my Amazon on sites.
