Amazon Gerente interview questions

One of the very long interview process ( 6-7 interviews and 8 to 9 people involved ) but end up scare you with very bad offer. HR is friendly in approach but confusing when comes to the whole process. Salary expectation requested before loop interview ( 5-6 interview) but end up after 7 interview the offer seemed scary and 50% below expectation. For those attending interview, better clear the salary expectation before going through loop interview, otherwise disappointment awaits.
