I recently interviewed at Amazon which had 3 virtual interviews. First two rounds were ok but the third interviewer was too bad.
He wasn't discussing stuff neither was he interested in discussing it. He told me a question and didn't even write it or give an example about it. The question had an API involved and he didn't even tell what the API needs or what it returns or how it returns.
It looked like I am driving the conversation and at one point I caught him yawning a bit. And also he wasn't interested in confirming if the optimizations i suggested were good enough or not. No hints or anything to indicate a lead. I did end up with a solution but he wasn't even telling me if that solution is acceptable.
So I am in a dilemma if I should email Amazon and tell about this experience and would it even matter.
Please advise.
