Amazon Data Engineer interview questions

Process is simple,First round is written test with simple sql queries .if that is done and all answers correct then second round will be also a written test with complex Sqls.candidate should be strong in sql.

The interview was well coordinated by a recruiter. Recruiter informed priorly what expected in the interview. Interview started with my current experience and then BI questions. Then interviewer started asking Data warehouse questions. I haven't informed to expect DW questions. So, i failed to answer to the full extent. Then asked some SQL coding. Interview was quite cool except DWH questions
