    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.
  5. 5

    Round 5

    Behavioral / Leadership

The Danger Zone: Top Reasons Candidates Fail

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

  • Not handling edge cases like empty input or timestamps that are not sorted.
  • Errors in summing the digits after doubling (e.g., not handling two-digit sums correctly).
  • Focusing solely on personal career advancement without demonstrating understanding of seQura's mission or impact.
  • Not demonstrating initiative beyond standard responsibilities.

Test Yourself: Real seQura Questions

Three real prompts pulled from our database.

Type · Motivation

Why are you interested in joining seQura, and what specifically about our work in the fintech space excites you as a Software Engineer?

Type · Code Clarity & Edge Cases

Write a function that takes a list of payment amounts and returns the total amount after applying a discount. The discount is 10% for amounts over $100, and 5% for amounts between $50 and $100. Amounts below $50 have no discount. Ensure your code is readable and handles edge cases.

Type · API Design

Design an API for a real-time payment processing system. Consider aspects like idempotency, request/response formats, error handling, and security for handling financial transactions.

  1. 2

    Type · Algorithmic

    Given a list of transaction IDs and their corresponding timestamps, write a function to find the number of transactions that occurred within a rolling 5-minute window. For example, if the window slides by 1 minute, we want to count transactions in `[t, t+5min]`.
  2. 3

    Type · Data Structures

    Implement a Least Recently Used (LRU) cache with a fixed capacity. The cache should support `get(key)` and `put(key, value)` operations. When the cache is full and a new item is inserted, the least recently used item should be evicted.

    Type · Scalability

    How would you design a system to handle a sudden surge in payment requests during a major online sale event (e.g., Black Friday)? Discuss potential bottlenecks and strategies to ensure high availability and low latency.

    Type · Algorithmic

    Given a stream of financial transactions, design a data structure that can efficiently calculate the median transaction amount at any point in time. Assume the stream can be very large.
  2. 7

    Type · Debugging

    A critical payment processing endpoint is intermittently failing with a 500 Internal Server Error. The logs show a generic 'database connection error' but it's not clear if the database is actually down or if there's another issue. How would you approach debugging this problem?
