The “Bar Raiser” isn’t a magic fix that can completely rescue a weak performance but if you’re already nearly there, they can help tilt the decision in your favor. In the Amazon Loop, the Bar Raiser’s job is to ensure that every new hire not only meets the technical requirements but also “raises the bar” by embodying Amazon’s Leadership Principles. They serve as an impartial checkpoint. In practice, if most of your interview rounds are strong and you clearly demonstrate the qualities Amazon values, the Bar Raiser is likely to back you up even if one area was a bit off. However, if you’re significantly below the required standard, the Bar Raiser’s veto power means they won’t “unfuck” the situation for you. Essentially, they can help smooth over minor issues when you’re already a strong candidate, but they won’t compensate for a poor overall performance.
This balance is why many candidates focus on showcasing consistent excellence throughout the interview process.
