Πόσο διαρκεί η διαδικασία συνέντευξης της American Express;

Οι περισσότεροι υποψήφιοι ξοδεύουν 4 έως 8 εβδομάδες από το screen recruiter μέχρι την προσφορά. Το ίδιο το onsite loop τρέχει σε μία μέρα ή χωρίζεται σε δύο μισές ημέρες, με debrief και προσφορά τυπικά μέσα σε 5 εργάσιμες ημέρες μετά.

Πώς πρέπει να προετοιμαστώ ειδικά για την American Express;

Εστιάστε σε τρία πράγματα: (1) στο DNA της εταιρείας που δείχνεται παραπάνω — τι βαθμολογούν πραγματικά, (2) στους γύρους του loop σας, ειδικά τον γύρο που οι περισσότεροι υποψήφιοι υποτιμούν, και (3) σε εξάσκηση στους τύπους ερωτήσεων αυτού του οδηγού χρησιμοποιώντας ένα δομημένο πλαίσιο όπως CIRCLES ή STAR.

Ισχύει αυτό για ρόλους engineering ή design στην American Express;

Το DNA παραμένει το ίδιο — αυτό που αλλάζει είναι ο συνδυασμός γύρων. Οι υποψήφιοι SWE αντιμετωπίζουν coding screens αντί για Product Sense· οι designers αντιμετωπίζουν portfolio reviews και ασκήσεις σχεδιασμού. Το «τι εκτιμούν» και τα συμπεριφορικά σήματα μεταφέρονται σε όλες τις λειτουργίες.

Type: Motivation. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Given a list of credit card transactions with timestamps, amounts, and merchant IDs, write a function to detect potentially fraudulent transactions. A transaction is considered potentially fraudulent if it occurs within 5 minutes of another transaction from the same merchant with an amount greater than $1000.

Type: Algorithm. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Implement a Least Recently Used (LRU) cache with a fixed capacity. The cache should support `get(key)` and `put(key, value)` operations. `get` should return the value if the key exists and mark it as recently used, otherwise return -1. `put` should insert or update the key-value pair, evicting the least recently used item if the cache exceeds capacity.

Type: Data Structure. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Design a system to process and analyze real-time credit card transaction data for fraud detection. Consider aspects like data ingestion, processing latency, storage, and alerting.

Type: System Design. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Design a rate limiter for API requests to protect backend services. Consider different strategies (e.g., token bucket, leaky bucket) and how to implement it in a distributed environment.

Given a dataset of customer purchase histories, implement a function to find the top K most frequently purchased items. Consider efficiency for large datasets.

Here is a code snippet that is supposed to calculate the average transaction amount for a given user, but it contains a subtle bug. Find and fix the bug. [Provide a code snippet with a bug, e.g., integer division, incorrect loop termination, off-by-one error, or mishandling of empty lists].

Type: Debugging. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Tell me about a time you had a significant disagreement with a cross-functional partner (e.g., engineering, marketing, sales). How did you approach it, and what was the outcome?

Type: Conflict Resolution. Sign up at JobMentis to see the full framework, grading signals, and worked answer for this question.

Tell me about a time you had to work with a difficult stakeholder or a team member with a different working style. How did you approach the situation, and what was the outcome?
