Capital One Assessment Test — Questions and Answers

Question 1: An analyst is evaluating two credit models. Model A has AUC-ROC of 0.82; Model B has AUC-ROC of 0.79 but captures 15% more high-risk customers. Which factor should drive the final model selection?

Always select the model with higher recall regardless of AUC
Flip a coin since the difference is within statistical noise
Business objective — if minimizing defaults is the priority, higher recall on high-risk customers may outweigh AUC (Correct answer)
Always select the higher AUC model regardless of business context

Correct answer: Business objective — if minimizing defaults is the priority, higher recall on high-risk customers may outweigh AUC

Model selection depends on business objectives; a lower AUC model that catches more high-risk customers may reduce losses more than one with marginally higher AUC.

Question 2: An analyst writes this Python code: df.groupby('state')['revenue'].agg(['mean','median','std']). What will this output?

A pivot table with states as columns
Three separate DataFrames, one for each aggregation
A DataFrame with mean, median, and standard deviation of revenue for each state (Correct answer)
A single row with overall mean, median, and standard deviation across all states

Correct answer: A DataFrame with mean, median, and standard deviation of revenue for each state

The groupby + agg call returns a DataFrame indexed by state with three columns: mean, median, and std of revenue.

Question 3: You are asked to complete an analysis but realize you are missing data from another department that has not responded to your requests. The deadline is tomorrow. What is the best action?

25
11 (Correct answer)

0.769 (Correct answer)
0.700

Correct answer: 0.769

F1 = 2 × (precision × recall) / (precision + recall) = 2 × (0.85 × 0.70) / (0.85 + 0.70) = 1.19 / 1.55 ≈ 0.769.

0.78:1
0.81:1
0.89:1
0.83:1 (Correct answer)

Correct answer: 0.83:1

To find this ratio, you need the number of hatchbacks produced in Germany and the number of convertibles produced in Germany. Divide the number of German-produced hatchbacks by the number of German-produced convertibles. Express this result as a ratio to 1. For example, if Germany produced 83 hatchbacks for every 100 convertibles, the ratio would be 0.83:1.

Both datasets have equal variability
Standard deviation cannot be used to compare variability between datasets
Dataset B has more variability than Dataset A (Correct answer)

A higher standard deviation indicates greater spread around the mean; Dataset B's standard deviation of 15 means its values are more spread out than Dataset A's.

Question 41: How much would two round-trip tickets for the quickest coach trip with breakfast cost in total?

£170 (Correct answer)
£270
£210
£220

Correct answer: £170

This calculation requires knowing the cost of a single one-way ticket for the quickest coach trip and the cost of breakfast. A round-trip ticket would typically cost double the one-way fare. If a one-way quickest coach trip costs £40 and breakfast is an additional £5 per person per round trip, then one round-trip ticket with breakfast would be (£40 * 2) + £5 = £85. Therefore, two such round-trip tickets would cost £85 * 2 = £170.

Having no outstanding loans
Free of regulatory scrutiny

7,587
4,667
3,611
5,393 (Correct answer)

Correct answer: 5,393

To find the difference, you must sum all domestic flight numbers for the years 2020, 2021, and 2022. Separately, sum all international flight numbers for the same three years. The final step is to calculate the absolute difference between these two cumulative sums (total domestic flights minus total international flights). The result of this calculation is 5,393.

Question 49: A memo reads: 'All associates must complete compliance training before quarter-end or face account access suspension.' An associate finishes training on the last day of the quarter. What is the correct interpretation?

The associate is compliant and retains access. (Correct answer)
The memo does not apply to this associate.
The associate is non-compliant because they waited too long.
The associate must redo the training next quarter.

A discrepancy in auditing refers to an inconsistency or mismatch between figures or records.

No, because the policy requires written authorization from a VP or above. (Correct answer)
Yes, if the decision is documented afterward.
Yes, because a manager's approval carries authority.
No, but only if the exception involves more than $10,000.

Correct answer: No, because the policy requires written authorization from a VP or above.

The policy specifies both the form (written) and the level (VP or above), and a verbal manager approval meets neither requirement.

Accept and give the vendor a favorable review in return
Accept it but don't disclose it
Politely decline and inform your manager or compliance team as required by policy (Correct answer)

$900
$315
$1,500
$1,050 (Correct answer)

'Duplicate charges rarely happen at Capital One.'
'Your account looks fine on our end.'
'Please call our hotline during business hours.'

Correct answer: 'We understand your concern and will review the March 5 transaction immediately.'

Acknowledging the specific concern (March 5 transaction) and committing to action demonstrates both active listening and empathy.

Question 59: In Python, which code snippet correctly identifies outliers in a list of transaction amounts using the IQR method?

Q1, Q3 = np.percentile(data, [25, 75]); IQR = Q1 - Q3; outliers = [x for x in data if x < Q1 - 1.5*IQR or x > Q3 + 1.5*IQR]
Q1, Q3 = np.percentile(data, [25, 75]); IQR = Q3 - Q1; outliers = [x for x in data if x < Q1 - 1.5*IQR or x > Q3 + 1.5*IQR] (Correct answer)
Q1, Q3 = np.percentile(data, [25, 75]); IQR = Q3 - Q1; outliers = [x for x in data if x < Q1 + 1.5*IQR or x > Q3 - 1.5*IQR]
mean, std = np.mean(data), np.std(data); outliers = [x for x in data if abs(x - mean) > 1.5*std]

Correct answer: Q1, Q3 = np.percentile(data, [25, 75]); IQR = Q3 - Q1; outliers = [x for x in data if x < Q1 - 1.5*IQR or x > Q3 + 1.5*IQR]

The IQR method defines outliers as values below Q1 - 1.5*IQR or above Q3 + 1.5*IQR, with IQR = Q3 - Q1.

25 percentage points
5 percentage points (Correct answer)
20 percentage points
1.25 percentage points

Correct answer: 5 percentage points

Percentage point change is the simple arithmetic difference between two percentages: 30% − 25% = 5 percentage points.

Question 66: Which sentence contains a logical inconsistency?

The project was completed on time and under budget.
The new policy improved security but also decreased all security incidents. (Correct answer)
Customer satisfaction rose after the service redesign.
The team increased revenue and reduced costs simultaneously.

Correct answer: The new policy improved security but also decreased all security incidents.

Saying a policy 'improved security but also decreased all security incidents' is self-contradictory—fewer incidents is a sign of improved security, not a contradiction of it, making the 'but' illogical.

df.apply(lambda row: row['state'] == 'CA' and row['balance'] > 5000, axis=1)
df[(df['state'] == 'CA') & (df['balance'] > 5000)] (Correct answer)
df[df['state'] == 'CA'][df['balance'] > 5000]
