The Flowdesk 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 Flowdesk interview outcomes, avoid these common traps:
- Incorrectly calculating the standard deviation of returns.
- Not addressing data partitioning, load balancing, or fault tolerance for high-volume data streams.
- Focusing on effort rather than outcome.
- Claiming to learn something without specific examples.

9 of 17 questions shown
Recruiter Screen
1- 1
Type · Motivation
What interests you about working at Flowdesk, a fintech company focused on digital asset trading infrastructure, compared to other opportunities you've explored?
Coding Screen
3- 2
Type · Algorithmic
Given a stream of real-time trade data (each trade has a price, volume, and timestamp), design an algorithm to calculate the volume-weighted average price (VWAP) over a rolling N-minute window. Assume trades arrive in chronological order. - 3
Type · Algorithmic
You are given a list of cryptocurrency pairs and their current exchange rates. Design a function to detect if there is a triangular arbitrage opportunity. For example, if you can trade BTC -> ETH -> XRP -> BTC and end up with more BTC than you started with. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Type · System Design
Design a real-time risk management system for a cryptocurrency exchange. It needs to monitor user positions, P&L, and margin levels, and trigger alerts or liquidations when thresholds are breached. Consider high throughput and low latency. - 5
Type · System Design
Design a system to ingest and process millions of real-time cryptocurrency trades per second from various exchanges. The system should be able to provide aggregated data (e.g., tick data, order book snapshots) with low latency. - + 1 more questions in this round (sign up to unlock)
Onsite Coding
3- 6
Type · Coding
Implement a function to calculate the Sharpe Ratio for a given series of historical portfolio returns. You'll need to handle potential edge cases like zero standard deviation. - 7
Type · Coding
Given a large dataset of historical trades for a specific asset, write a function to find the best execution price for a large order. This involves considering trade-offs between market impact (larger orders move the price) and time (waiting for better prices). You can simplify by assuming a fixed market impact model. - + 1 more questions in this round (sign up to unlock)
Behavioral / Leadership
7- 8
Type · Ownership
Tell me about a time you took ownership of a complex technical problem or project that wasn't strictly in your job description. What was the situation, what did you do, and what was the outcome? - 9
Type · Collaboration
Describe a situation where you had a significant technical disagreement with a colleague or team lead. How did you approach the discussion, and what was the resolution? - + 5 more questions in this round (sign up to unlock)
