Δοκιμάστε τον εαυτό σας: Πραγματικές ερωτήσεις Alan

Τρία πραγματικά prompts τραβηγμένα από τη βάση δεδομένων μας.

Τύπος · System Design

Design a system to process and categorize user spending from bank transaction data. Consider data ingestion, categorization logic (rule-based and potentially ML-based), storage, and how to serve this data to the frontend.

Τύπος · Algorithm

Given a list of financial transactions (each with a timestamp, amount, and user ID), write a function to calculate the daily spending for each user. Handle potential duplicates and out-of-order timestamps.

Τύπος · Past Experience

Tell me about a time you had to influence a senior stakeholder or a cross-functional team to adopt your product vision or strategy when they were initially resistant.
