BIE role at Amazon

Hello,

I am looking for advice from folks working as Business Intelligence Engineers (BIE) at Amazon. What has been your experience and what kind of work is involved in that role?

My brother is a data analyst and he is considering the BIE role as a stepping stone towards Data Engineering roles. How true is this?

SIXT is also another company that offers BIE roles.

Please let me know your thoughts.
