The seQura DNA (TL;DR)
The seQura Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3
Round 3
System DesignDistributed systems, trade-offs at scale, architecture under constraints. - 4
Round 4
Onsite CodingLeetCode-hard, debugging, code clarity, edge cases. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
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.

9 of 21 questions shown
Recruiter Screen
1- 1
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?
Coding Screen
3- 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]`. - 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. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
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. - 5
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. - + 1 more questions in this round (sign up to unlock)
Onsite Coding
3- 6
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. - 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? - + 1 more questions in this round (sign up to unlock)
Behavioral / Leadership
11- 8
Type · Ownership
Tell me about a time you took ownership of a project or problem that was not explicitly part of your job description. What was the situation, what did you do, and what was the outcome? - 9
Type · Ownership
