Amazon Knowledge Engineer interview questions

Applied to Amazon via an employee referral. A week later I was given a phone interview and a week after that I was invited to an onsite interview. Overall the entire process was very quick and very prompt. The phone interview was difficult and it included questions about how Alexa could potentially return answers for questions with multiple possible responses, what to identify in a dataset, and what my proudest and least proud moments were in my career. Additionally what my experience was with Alexa and do I use Alexa for Q&A. The onsite interview was additionally difficult, but was a lot more interactive and fun than I was expecting. One of my interviewers was not enthuastic and seemed unhappy to be there, but otherwise everyone was a pleasure to be around. One thing to keep in mind: Amazon has a policy of not disclosing the compensation scale for a role. I reached out to my point of contact for a compensation scale and we had a phone call where we discussed what my base salary was and if it was within the ballpark for what was being offered. Amazon claims that they base offer packages on your experience and what you bring to the team, so they do not offer a pay scale before the onsite interview.

First round interview was over the phone. It began by asking a few behavioral questions, then immediately jumped into technical questions. They gave no indication they would ask technical questions right off the bat. They took a longer time than they said they would.
