Tell Me About a Time You Investigated a Problem Nobody Else Could Solve - Bar Raiser Evaluate

Evaluate These Two Answers

"Tell me about a time you had to dive deep to solve a problem that was not initially assigned to you or part of your team's scope."

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 routine sprint, my manager suggested I look into this since I had bandwidth because we found an increase in error rates in the payment system. I collaborated with the team to investigate the logs and identified a race condition causing intermittent failures. We then deployed a fix that stabilized the system. Although it improved, I believe more analysis is needed to prevent future issues.

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

Candidate B

While reviewing system metrics unrelated to my team, I noticed a 25% spike in payment processing errors that had no existing ticket or owner. I independently initiated a deep dive by analyzing logs and tracing the issue to a race condition in the transaction handler. I designed and implemented a fix that reduced errors by 30% within two weeks, improving customer experience and reducing support tickets. I also documented the root cause and recommended monitoring enhancements to prevent recurrence.

🚨

Auto-Fail Markers

Manager-directed ownership

"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 an increase in error rates"

Using 'we' obscures candidate's individual ownership and initiative, weakening ownership signal and clarity of contribution.

📝

Bar Raiser Notes

Ownership weak - manager-directed; collective language obscures individual contribution; minimal quantified impact; limited action specificity; self-awareness present but insufficient; No Hire.

Fix-It Challenge

Ownership initiation

Before"my manager suggested I look into this since I had bandwidth"

→

After"I noticed the error spike during a routine review with no ticket or owner, so I decided to investigate on my own initiative"

Demonstrates self-initiation and ownership rather than manager assignment, critical for Amazon Dive Deep.

Individual contribution clarity

Before"we found an increase in error rates"

→

After"I found an increase in error rates"

Clarifies candidate's personal ownership and responsibility for discovery.

Quantified impact detail

Before"Although it improved, I believe more analysis is needed to prevent future issues."

→

After"My fix reduced errors by 30%, improving system stability and customer satisfaction."

Adds concrete metric and business impact, strengthening quantified impact signal.

Coaching Notes

• At Amazon, Dive Deep requires clear ownership signals starting with self-initiation, not manager direction.
• Avoid collective 'we' language that dilutes individual contribution; use 'I' to highlight personal ownership.
• Quantify impact with metrics and explain business relevance to demonstrate true depth of understanding.
• Structure answers with clear task, multiple specific actions starting with 'I', and measurable results.
• Self-awareness should reflect lessons learned or next steps to show continuous improvement mindset.

Model Answer Guidance

A strong Dive Deep answer at Amazon starts with the candidate noticing an issue independently (e.g., 'I noticed a spike in errors with no ticket or owner'), followed by multiple specific actions they personally took ('I analyzed logs, traced root cause, designed and deployed fix'), and concludes with quantified impact ('reduced errors by 30%, improving customer experience'). Avoid phrases indicating manager assignment or collective team ownership. Include self-awareness by describing what was learned or recommended next steps.
