Amazon Non Software Development Engineer interview questions

I initially applied online through Amazon Jobs page and received a reply to complete the Online Assessments in March. I completed 3 rounds of OAs over a span of 2 weeks and received the invitation to the Final Interview which I had it scheduled for May. The final virtual on-site interview consisted of 3 sessions, each being 45 minutes long. For each session, around 10-15 minutes are spent first with behavioural type questions on variuos Leadership Principles, and the rest are spent for Data Structure and Algorithms type questions. The DS&A questions were usually started off with a very simple question, and when I got it correctly, they built up from the question with additional constraints/performance improvements. It took them 5 business days to get back to me with the result.

Smooth, nothing special. Just go the provided site, complete the online assessment within the time limit. Though, the invitation email to the online assessment went to junk mail. It's hard to know if you're invited.
