Tell Me About a Time You Made a Difficult Decision With Incomplete Information - Bar Raiser Evaluate

Evaluate These Two Answers

"Tell me about a time you made a decision with incomplete data and how you ensured it was the right choice."

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 rubric weights.

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, my manager suggested I look into this since I had bandwidth. I identified a latency issue affecting checkout times. I collaborated with the team to find root causes and deployed a fix. The latency improved by approximately 20%, reducing checkout delays and improving customer satisfaction. This was part of our ongoing efforts to improve system performance.

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

Candidate B

While reviewing system logs, I noticed an unusual spike in checkout latency that wasn’t assigned to my team and had no existing ticket. I weighed the risks and benefits, acted with about 70% of the data available, and decided to investigate proactively. I isolated a race condition causing delays, implemented a fix that reduced latency by 30%, which improved customer checkout success rates by 5%. I monitored outcomes closely and iterated on the solution based on real-time feedback, ensuring the fix was robust and scalable.

manager-directed task assignment

"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 latency issue"

Using 'we' obscures candidate’s individual ownership and decision-making. Lowers ownership_signal score significantly.

Bar Raiser Notes

Ownership weak - manager-directed; collective language obscures individual role; no quantification of impact; no self-awareness or learning described; No Hire.

Fix-It Challenge

ownership phrasing

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

→

After"I noticed the issue during a routine review and decided to investigate proactively without being asked"

Demonstrates self-initiation and ownership rather than manager assignment

individual contribution clarity

Before"we found a latency issue"

→

After"I identified a latency issue"

Clarifies candidate’s personal role and decision-making responsibility

quantify impact

Before"The latency improved by approximately 20%, reducing checkout delays and improving customer satisfaction"

→

After"The latency improved by approximately 20%, reducing checkout delays and improving customer satisfaction"

Quantifies impact to show business value and result of candidate’s actions

Coaching Notes

• At Amazon, Are Right a Lot means candidates must demonstrate strong ownership by initiating investigations themselves rather than acting on manager direction; phrases like 'my manager suggested' are fatal ownership disqualifiers.
• Use precise individual language instead of collective 'we' to highlight your personal role in decision-making and problem-solving.
• Quantify impact with metrics and business outcomes to show the real-world effect of your decisions.
• Describe how you balanced incomplete data, monitored outcomes, and iterated on your solution to demonstrate sound judgment and learning.
• Avoid vague or generic statements; Amazon Bar Raisers look for concrete examples of weighing risks and benefits and acting decisively with partial data.

Model Answer Guidance

A strong answer clearly states the candidate’s own initiative to identify and solve a problem without managerial prompting, uses specific individual language, quantifies the impact with metrics, and explains how they monitored and iterated on the solution. For example, 'I noticed an unusual spike in latency not assigned to my team and no ticket existed; I weighed risks with 70% data, isolated a race condition, implemented a fix reducing latency by 30%, and monitored outcomes to ensure robustness.' This signals ownership, good judgment, and measurable impact aligned with Amazon’s Are Right a Lot principle.

Practice

1. You faced a situation where you had to make a critical decision with incomplete data. You gathered all available information, consulted experts, and used your judgment to choose the best path forward. Which Amazon Leadership Principle does this primarily demonstrate?

easy

A. Are Right a Lot

B. Bias for Action

C. Customer Obsession

D. Deliver Results

Solution

1. Step 1: Identify the core behavior -- making decisions with incomplete data.
2. Step 2: Recognize that this reflects strong judgment and good decision-making.
3. Step 3: Bias for Action emphasizes speed, but here the focus is on correctness despite uncertainty.
4. Step 4: Are Right a Lot is about good judgment and making sound decisions even with limited information -> Are Right a Lot

Hint: Decision with incomplete data -> Are Right a Lot

Common Mistakes:

2. Candidate answer: "My manager asked me to analyze a drop in sales. I reviewed the data and found some inconsistencies. We then fixed the issue, and the team was happy with the results. I think it improved our process." What is the PRIMARY weakness in this answer?

easy

A. Manager-assigned investigation -- no self-initiation

B. Weak reflection on the impact

C. No second-order effect mentioned

D. Vague description of actions taken

Solution

1. Step 1: Identify who initiated the action -- the candidate says 'My manager asked me'.
2. Step 2: This shows lack of self-initiation, which is a fatal flaw for Are Right a Lot.
3. Step 3: Other issues like weak reflection or vague actions are secondary and fixable.
4. Step 4: Therefore, the primary weakness is manager-assigned investigation -> Manager-assigned investigation -- no self-initiation

Hint: Manager asked -> no ownership, fatal flaw

Common Mistakes:

3. In a candidate's answer, they say: "I used data from multiple sources to validate my hypothesis before making the decision." Which Amazon Leadership Principle does this sentence primarily demonstrate?

medium

A. Bias for Action

B. Dive Deep

C. Are Right a Lot

D. Invent and Simplify

Solution

1. Step 1: Identify the behavior -- validating hypothesis with multiple data sources.
2. Step 2: Dive Deep involves thorough investigation, but the focus here is on making the right decision.
3. Step 3: Are Right a Lot emphasizes good judgment and using data to be correct.
4. Step 4: Therefore, this sentence primarily signals Are Right a Lot -> Are Right a Lot

Hint: Data validation before decision -> Are Right a Lot

Common Mistakes:

4. What does the phrase "My manager asked me to investigate the issue" signal to the interviewer?

medium

A. Reflects strong time management skills

B. Shows good communication with management

C. Demonstrates proactive problem identification

D. Indicates task assignment, ownership signal destroyed

Solution

1. Step 1: Identify who initiated the action -- the manager.
2. Step 2: This means the candidate did not self-initiate the task.
3. Step 3: Lack of ownership is a critical negative signal in behavioral interviews.
4. Step 4: Therefore, the phrase signals task assignment and destroys ownership -> Indicates task assignment, ownership signal destroyed

Hint: "Manager asked" -> ownership lost, task assigned

Common Mistakes:

5. Candidate answer: "I noticed a recurring error in our system logs and decided to investigate without waiting for direction. I gathered data from multiple teams and identified the root cause. After analyzing options, I proposed a fix that reduced errors by 30%. We collectively decided to implement the solution, and the team saw improved stability. I also documented the process to prevent future issues." Which element is the disqualifier?

hard

A. "I noticed a recurring error and decided to investigate without waiting for direction."

B. "We collectively decided to implement the solution."

C. "I proposed a fix that reduced errors by 30%."

D. "I gathered data from multiple teams and identified the root cause."

Solution

1. Step 1: Identify who initiated the investigation -- candidate self-initiated (good).
2. Step 2: Candidate gathered data and proposed a fix with measurable impact (strong signals).
3. Step 3: The phrase "We collectively decided" dilutes individual ownership and decision-making.
4. Step 4: This subtle disqualifier weakens the Are Right a Lot signal -> "We collectively decided to implement the solution."

Hint: "We collectively decided" -> ownership diluted, subtle disqualifier
