Amazon Data Engineer interview questions

Well planned and executed. Candidates are well informed.

The interviews are generally long and go on for a day and if you think you did really well, dont expect the outcome to be positive. I had a total of 2 interviews over the phone which was completely technical with a bunch of SQL questions and scenarios. Then I was called for an In-Person interview with overall 8 people. About 4 interviews including the lunch interview was full of SQL questions with a lot of white-boarding. I was about to end the day on a high note but surprisingly it ended up with C# and Algorithm questions, which really baffled me (especially for a data engineer position). I was sure of getting the offer but I did not!!
