Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 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 Young Platform interview outcomes, avoid these common traps:
- Describing a task that was part of their job description.
- Describing a situation without explaining their own actions or thought process.
- Generic answers not tailored to Young Platform or fintech.
- Inefficiently iterating through one list for each element in the other list (O(N*M)).

Recruiter Screen
1- 1
Type · Motivation
Why are you interested in working at Young Platform, and what excites you about the fintech space specifically?
Coding Screen
3- 2
Type · Algorithmic
Given a list of user transactions with timestamps, write a function to find the user with the highest transaction volume within any given 1-hour window. Assume transactions are sorted by time. - 3
Type · Data Structures
Implement a data structure that supports adding a new crypto asset price, retrieving the current price of any asset, and efficiently calculating the volume-weighted average price (VWAP) for a specific asset over the last N minutes. Assume prices arrive in chronological order. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Type · Architecture
Design a system to detect and prevent fraudulent crypto transactions in real-time. Consider the data sources, processing pipeline, detection algorithms, and alerting mechanisms. - 5
Type · Scalability
How would you design the backend for a feature that allows users to stake their crypto assets on Young Platform? Consider aspects like security, transaction processing, reward distribution, and scalability to handle millions of users. - + 1 more questions in this round (sign up to unlock)
Onsite Coding
4- 6
Type · Debugging
A user reports that their recent trade history is not displaying correctly in the app – some trades are missing, and others show incorrect amounts. Here's a simplified log snippet and the relevant code. Debug and explain the root cause and how you'd fix it. - 7
Type · Algorithm
Implement a function to calculate the optimal execution price for a large crypto trade, considering a limit order book. The function should take the desired trade size and the order book (list of bids and asks with prices and quantities) as input, and return the minimum cost to execute the trade or the maximum proceeds if selling. - + 2 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 assigned to you. What was the situation, what did you do, and what was the outcome? - 9
Type · Conflict Resolution
