Amazon Data Engineer interview questions

Ridiculous process, punctuated by the fact that one of the interviewer's in my loop was a senior data engineer that seemed to not know basic data modeling and warehousing theories and concepts. This interviewer also could barely speak English, and I spent half the time trying to explain stuff to her that she couldn't comprehend due to her poor English proficiency. The technical questions weren't that difficult, what's tough about the process are the redundant leadership questions. They tend to ask you the same question over and over again across different loops, and expect a different answer every time. Suffice to say, I didn't get an offer and that's probably a good thing. It's not hard to see why there's so much employee turnover there.

In the hackerrank testing interface, you have to answer two highly technical problems that must pass 30 test instances. Then you give written feedback of the computational complexity, choices in solutions, etc.
