American Express Online Assessment: 2-3 Coding Tasks, 4 Aptitude Tests

Last updated: October 2026

Quick Answer

The American Express online assessment is a timed test whose shape depends on the track. Software candidates report a Codility or HackerRank coding test with two or three easy-to-medium problems in roughly 75-90 minutes. Early careers and campus candidates report aptitude tests (numerical, verbal, logical) plus a situational judgement test, often attributed to SHL. Drill timed sets with OphyAI Coding Interview and rehearse the rounds after it in OphyAI Interview Practice.

Part	What is reported
Tech platform	Codility (2025 intern reports) or HackerRank
Coding problems	2-3, LeetCode easy to medium; one report adds a debugging task
Coding time	75-90 minutes reported
Campus and non-tech	Numerical, verbal, logical, situational judgement (prep sites)
Analyst variants	Logical reasoning and SQL sections
Next step	A HireVue video interview, then live rounds or an assessment centre

What American Express Is Testing in This Round

It is a filter, not a deep evaluation. The coding test checks whether you can write correct, efficient code under a clock, graded by hidden test cases. The aptitude tests check speed and accuracy. The situational judgement test checks your instincts against the Blue Box Values in the American Express interview guide. Amex publishes no pass marks.

Red flags that fail candidates:

• Failing hidden edge cases (empty input, duplicates, large arrays). One 2020 campus report says most test cases were hidden.
• A brute-force answer that times out when an O(n) or O(n log n) approach exists.
• Running out of clock on the numerical test.
• SJT answers that please the customer by bending a rule.

What to Expect

All of this is candidate-reported or from prep sites; Amex does not publish the format.

• Software and tech internships. A November 2025 Glassdoor internship review describes a Codility challenge with two coding questions, a HireVue of four or five behavioral questions in about 20 minutes, then an in-person assessment centre. Another 2025 review reports the same sequence.
• Experienced software roles. One GeeksforGeeks experience describes a 90-minute HackerRank challenge with two coding problems and one debugging problem; a 2018 graduate report describes 75 minutes of multiple-choice plus coding. Reported topics: strings, binary search trees, sorting, complexity and OOP.
• Data and analyst roles. A 2025 data analyst report describes logical reasoning and SQL sections; one analyst intern describes a HireVue coding round with Pandas and SQL.
• Campus, graduate and non-tech roles. Prep sites list four tests: numerical (charts and tables), verbal, logical (abstract patterns) and a situational judgement test where you rate or rank responses. AssessmentDay says Amex usually uses SHL but that this varies by location and role.

Example Questions and How to Answer Them

Reported themes, not leaked questions.

1. A string manipulation problem

Approach: clarify case and empty input, solve in one pass with a hash map or two pointers, then test an empty string and one character.

2. A binary search tree task

Approach: state the BST property, choose recursion or an explicit stack, and check the skewed tree that makes O(log n) into O(n).

3. Debug an existing function

Approach: trace the smallest failing input, find the off-by-one or wrong condition, and change as little as possible.

4. A numerical reasoning item from a table

Approach: read the question first, find only the columns it needs, and round at the end.

5. A situational judgement scenario

A card member disputes a valid fee. Approach: acknowledge the customer, follow policy, escalate where appropriate. “Waive it quietly” is weak.

How to Prepare in 3 Days

• Day 1: patterns. Engineers: four problems each on strings, hash maps and trees from our coding interview examples. Campus candidates: one untimed set per test type.
• Day 2: the clock. Engineers: two sittings of three problems in 75 minutes, easiest first, 10 minutes kept to re-test. On Premium, review missed problems in OphyAI Coding Interview after the timer stops. Campus candidates: one timed set per test.
• Day 3: logistics. Use a laptop, read the invitation’s limits, then run a voice mock in OphyAI Interview Practice for the HireVue that follows.

Take the test unaided: Amex’s careers AI guidelines say AI use that misrepresents your own work or abilities may lead to disqualification, while practicing with AI is fine. See which companies allow AI in interviews.

Common Mistakes

• Trusting the sample tests. Test edge cases yourself.
• Getting stuck. Two submitted easy solutions beat one unfinished medium.
• Guessing the platform. Read the invitation and try the platform’s demo.

Frequently Asked Questions

Does American Express use HackerRank or Codility?

Both appear in candidate reports. The 2025 internship reviews we found describe Codility, while other software reports, including older graduate ones, describe HackerRank. The platform differs by team, country and year, so trust your invitation; the preparation is the same for both platforms.

How many questions are on the American Express coding assessment?

Reports range from two to three coding problems, sometimes with a debugging task or multiple-choice questions added. Difficulty is reported as LeetCode easy to medium. Amex does not publish a count, so check the number of questions and the time limit on the start screen before you begin.

What aptitude tests does American Express use?

Prep sites list numerical, verbal and logical reasoning tests plus a situational judgement test for early careers and graduate programs, and AssessmentDay says Amex usually uses SHL. Neither Amex nor SHL confirms this publicly, and it varies by location and role, so ask your recruiter which tests and publisher apply.

Can I use AI during the American Express online assessment?

No. Amex’s careers AI guidelines say inappropriate AI use during recruitment, including use that misrepresents your own work or abilities, may lead to disqualification, and list using AI to generate interview answers as not acceptable. The same page treats practicing interview questions with AI as fine, so prepare with AI and take the test on your own.

What happens after the American Express online assessment?

Candidates usually report a recorded HireVue next, then live technical or hiring manager rounds, or an assessment centre with group and solo exercises for internships and graduate programs. Timelines vary by role and region, so ask your recruiter for dates. The HireVue spoke covers the video round in detail.
