Tell Me About a Time You Challenged Unnecessary Spending or Waste - Bar Raiser Evaluate

Evaluate These Two Answers

"Tell me about a time you saved costs or resources by doing more with less, especially when the problem wasn't assigned to you or your team."

SDE 2⏱ 3 minAmazon Bar Raiser. LP evaluated explicitly. Content scored, not delivery.

Score BOTH candidates on Ownership Signal, Action Specificity, and Quantified Impact BEFORE applying the full rubric.

If you scored Candidate A >40 total, your calibration is biased toward fluency. Bar Raisers ignore delivery and score content only.

Candidate A

During a sprint focused on improving checkout latency, my manager suggested I look into this since I had bandwidth. While reviewing logs, I found a recurring timeout issue affecting payment processing. I identified the root cause as a misconfigured retry policy and deployed a fix. This reduced errors by 25%, saving $10,000 weekly in lost transactions and improving customer satisfaction. Although it wasn’t originally my task, I contributed to resolving the issue alongside the team.

Fluent delivery, confident tone - most untrained evaluators score this high

Candidate B

I noticed during a routine system audit that payment processing errors were spiking, but this wasn’t on my sprint and no ticket had been filed. Nobody had asked me to investigate, so I took initiative to dig into the logs and discovered a misconfigured retry policy causing timeouts. I proposed a permanent fix, implemented it, and monitored the results. This reduced errors by 30%, saving approximately $12,000 weekly in lost transactions and improving customer satisfaction scores. By acting without prompting, I prevented further revenue loss and reduced operational overhead.

Auto-Fail Markers

manager-directed task

"Candidate A - my manager suggested I look into this since I had bandwidth"

Ownership requires self-initiation. Manager-assigned = execution. Score 1 on ownership_signal (weight=30) = No Hire always.

collective language hiding individual contribution

"Candidate A - we found a recurring timeout issue"

Using 'we' obscures candidate’s individual ownership and initiative, reducing ownership_signal score to 1, which is fatal.

Bar Raiser Notes

Ownership weak - manager-directed; collective language obscures individual contribution; zero quantification in impact; no clear self-awareness; No Hire.

Coaching Notes

• At Amazon, Frugality means doing more with less by proactively identifying and fixing issues without waiting for assignment; ownership signal requires self-initiation, not manager direction.
• Avoid collective language like 'we found' that dilutes individual contribution; always highlight your personal role in the solution.
• Quantify impact with concrete metrics and business outcomes to demonstrate the value of your frugal solution.
• Show awareness of the broader business effect and how your action prevented waste or saved costs.
• Strong answers explicitly state that the problem was not on their sprint or team and that no ticket was filed, emphasizing initiative.

Model Answer Guidance

Strong answers start with a clear statement of noticing a problem that was not assigned or on their sprint, emphasizing self-initiation (e.g., 'I noticed', 'no ticket filed'). They describe specific actions taken with at least three sentences starting with 'I' to show personal ownership. The result section quantifies impact with metrics (e.g., error reduction %, cost savings) and explains business relevance (e.g., revenue saved, customer satisfaction improved). Avoid phrases indicating manager direction or collective 'we' language. Demonstrate self-awareness by reflecting on the broader impact and lessons learned.
