    Round 3

    System Design
    Distributed systems, trade-offs at scale, architecture under constraints.
  4. 4

    Round 4

    Onsite Coding
    LeetCode-hard, debugging, code clarity, edge cases.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of TODUBA interview outcomes, avoid these common traps:

  • Ignoring potential data privacy and security concerns specific to financial data.
  • Introducing new bugs or regressions during refactoring.
  • Describing a task that was clearly part of their job responsibilities.
  • Implementing a rate limiter on a single node, which doesn't scale.

  1. 2

    Type · Algorithmic

    Given a stream of financial transactions, design an algorithm to detect fraudulent patterns in real-time. Assume transactions have fields like `user_id`, `amount`, `timestamp`, `merchant_id`, and `transaction_type`. Focus on efficiency for a high-volume stream.
  2. 3

    Type · Algorithmic

    Implement a function that takes a list of user IDs and their associated transaction amounts, and returns the top K users with the highest total spending. Optimize for cases where the list is very large and K is relatively small.

  2. 5

    Type · System Design

    Design a notification system for TODUBA that alerts users about important account activities (e.g., large transactions, login attempts from new devices, upcoming bill payments). The system must handle millions of users and various notification channels (SMS, push, email).
