The Harmattan AI 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 problems, reasoning about defects, 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 Harmattan AI interview outcomes, avoid these common traps:
- Underestimating the volume and velocity of satellite imagery data.
- Incorrectly calculating the satellite's position relative to the Earth's terminator.
- Focusing on the speed of the deployment without explaining the safety or recovery mechanisms implemented
- Choosing a monolithic architecture instead of a scalable, distributed one.

8 of 11 questions shown
Recruiter Screen
1- 1
Type · Motivation
What interests you about working on aerospace software at Harmattan AI, and how do your skills align with our mission to advance satellite technology?
Coding Screen
3- 2
Type · Algorithmic
Given a stream of satellite telemetry data (timestamp, sensor_id, value), write a function to detect anomalies where a sensor reading deviates by more than 3 standard deviations from its rolling 1-hour average. Assume you have access to a data stream interface. - 3
Type · Algorithmic
You are given a 2D grid representing a satellite's sensor coverage map. Some cells are blocked (obstacles). Find the shortest path for a satellite to travel from a starting point to a target point, avoiding obstacles. Return the path length. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Type · System Design
Design a system to process and analyze real-time imagery from a constellation of Earth observation satellites. Consider data ingestion, storage, processing pipelines, and serving results to various clients (e.g., researchers, disaster response teams). - 5
Type · System Design
How would you design a system for coordinating a swarm of small satellites for a specific mission (e.g., distributed sensing)? Focus on communication protocols, consensus mechanisms, and handling potential failures or communication loss. - + 1 more questions in this round (sign up to unlock)
Onsite Coding
1- 6
Type · Algorithmic
Implement a function to calculate the precise time of satellite sunrise/sunset over a given geographical coordinate for a specific date, considering atmospheric refraction and the satellite's orbital parameters. Assume you have access to orbital propagation libraries.
Behavioral / Leadership
3- 7
Type · Behavioral
STARTell me about a time you had to work with a complex, poorly documented legacy system. What steps did you take to understand it, and what was the outcome? - 8
Type · Behavioral
STARDescribe a challenging technical problem you encountered on a past project related to real-time data processing or embedded systems. How did you approach debugging and resolving it, and what did you learn? - + 1 more questions in this round (sign up to unlock)

Frequently asked questions
How long does the Harmattan AI interview process take?
Most candidates spend between 4 and 8 weeks from recruiter screen to offer. The onsite loop itself runs in a single day or is split across two half-days, with debrief and offer typically within 5 business days after.
How should I prepare specifically for Harmattan AI?
Focus on three things: (1) the company DNA shown above - what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.
Does this apply to engineering or design roles at Harmattan AI?
The DNA stays the same - what changes is the round mix. SWE candidates face coding screens instead of Product Sense; designers face portfolio reviews and design exercises. The "what they value" and behavioral signals carry across all functions.
