Amazon Finance Analyst interview questions

It took nearly a month to get a call back after I've applied online. Asked to have a test at first, was not that easy. Needed a calculator. Mainly time constraint. Then an HR interview via phone. Their phone has been disconnected a few times but they managed to call again with a different line and it was okay. Mainly went through CV. Asked specific questions on a few things they've seen on CV. A perfect feedback session at the end. Not to criticize but a constructive one to guide me before I speak to Hiring Manger if I could manage to pass this level. (be more curios, ask more questions, give more examples with numbers, etc.) Sent a test afterwards, very similar to the first one. Again not easy questions with a need of calculator, but time seems challenging. there are 18 questions and you need to take your chance to finish the all of them. My score was not adequate enough in my opinion(13/18), yet they have set a call with hiring manager. Hiring manager interview was again via phone. He started with explaining his career and the structure of the organization and where the position is within it. then the line disconnected again. He said that he will ask HR colleagues to set another call another day to fix the connection issue, but I've got no call back again. - probably the score was not satisfactory and the did not want to lose time and proceeded with another applicant. Both HR colleague and Hiring Manager were so kind and felt me good while talking. But it would have been nice if they could have informed me that the process is over.
