An Amazon Bar Raiser breaks down the three common interview pitfalls: prepping only for technical rounds, parroting leadership-principle buzzwords, and leaning on a single impressive story. Each mistake masks a lack of consistent, real-world behavior that predicts on-the-job success.

• Candidates who ace technical rounds but can't answer behavioral questions get rejected, since most Amazon exits stem from behavioral issues rather than technical failures.
• Reciting Leadership Principle buzzwords doesn't work if the underlying story just describes routine assigned work rather than genuine initiative.
• Relying on one polished story as a crutch backfires because Amazon interviews probe multiple traits (ownership, inventiveness, customer obsession) that a single anecdote can't cover.
• Bar Raisers can veto any hire, even a referral from Jeff Bezos himself, if the candidate wouldn't outperform half the current employees at that level.

The author shares key lessons from conducting nearly 1,000 interviews at Amazon, emphasizing that technical skills alone aren't enough to secure a job. Candidates often fail due to poor self-presentation and lack of preparation for behavioral questions. Investing time in storytelling and delivery can significantly improve interview outcomes.

• Candidates spend ~95% of prep time on technical skills, but behavioral rounds are what actually sink most rejections.
• Just 10 hours of dedicated story preparation can meaningfully change interview outcomes.
• Unpracticed delivery causes rambling; treating interview answers like a work presentation (rehearsed and concise) fixes this.
• Fit with the team, not raw technical ability, is the final deciding factor in hiring.
