Amazon Operations interview questions

After successfully completing this process I did two back-to-back phone interviews with Amazon managers. Questions where again of the bahavioural type. At this stage I was also given the chance to ask questions about Amazon and the work position.

I had to answer a math question and then they called me, one interview was for personality asking about our experiences and stuff and the other was about the math question so you could explain your reasoning
