The Harmattan AI Interview Loop

Your onsite loop will typically consist of 5 rounds.

  1. 1

    Round 1

    Recruiter Screen
    Motivation, role fit, logistics.
  2. 2

    Round 2

    Coding Screen
    LeetCode-medium algorithmic problems under time pressure.
  3. 3

    Round 3

    System Design
    Distributed systems, trade-offs at scale, architecture under constraints.
  4. 4

    Round 4

    Onsite Coding
    LeetCode-hard problems, reasoning about defects, code clarity, edge cases.
  5. 5

    Round 5

    Behavioral / Leadership
    Past 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.

Test Yourself: Real Harmattan AI Questions

Three real prompts pulled from our database.

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?

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.

Type · Behavioral

STAR
At Harmattan AI, we prioritize the speed of relevance, which often means shipping software to satellites before every edge case is perfectly modeled. Tell me about a time you made a deliberate decision to deploy a system with known limitations to meet a mission-critical deadline. How did you document these risks, and what was your plan for addressing them post-deployment?

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.
