3- 2
Type · 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. - 3
Type · Algorithm
Implement a function to detect potential fraudulent transactions. Given a list of transactions and a set of rules (e.g., transactions over $1000 from a new user within 24 hours), identify suspicious ones. Assume rules can be complex and dynamic. - + 1 more questions in this round (sign up to unlock)
System Design
4- 4
Type · 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. - 5
Type · System Design
Design a real-time notification system for users about significant account activity (e.g., large deposits, low balance alerts, potential fraud). How would you ensure low latency and high availability? - + 2 more questions in this round (sign up to unlock)
Onsite Coding
4- 6
Type · Algorithm
Write a function to calculate the moving average of a user's transaction amounts over a rolling window of N days. Optimize for scenarios where new transactions are added frequently. - 7
Type · Debugging
A user reports that their spending summary for last month is incorrect. Here's a snippet of the relevant code and logs. Identify the bug and fix it. - + 2 more questions in this round (sign up to unlock)
