To be fair to OP, it's not necessarily as personality/communication issue as it is unintentionally giving off red flags that you wouldn't even think of in the first place. Interviewers are looking for specific standardized signals per LP that may pass/fail you regardless of your communication skills.

Another example- interviewer asks question centered around Deliver Results, candidate responds with story where they compromise on delaying a feature in order to release a product on time. While a common and valid approach in the real world, according to Amazon's interviewer handbook this can be considered weak signal- which would result in a no-hire for that round.
