The Open Cosmos DNA (TL;DR)

They seek individuals who can translate complex technical challenges into actionable plans for satellite missions. Expect to discuss trade-offs made during the design of their DragonFly satellite bus.

The Open Cosmos Interview Loop

Your onsite loop will typically consist of 5 rounds.

1
Round 1
Recruiter Screen
Motivation, operations background, supply chain interest.
2
Round 2
Operations Case
End-to-end supply chain optimization, bottleneck diagnosis, network design.
3
Round 3
Forecasting & Planning
Demand planning, S&OP, inventory optimization, working with statistical and ML forecasts.
4
Round 4
Optimization
Linear programming intuition, route optimization, facility location, trade-offs between cost/service/CO2.
5
Round 5
Behavioral / Leadership
Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Open Cosmos interview outcomes, avoid these common traps:

Failing to mention any specific aspect of Open Cosmos's business model or operations.
Not considering the impact of rapid technological advancement and miniaturization.
Vaguely identifying 'testing' as the bottleneck without pinpointing specific equipment, personnel, or process steps.
Proposing a static solution without considering future scalability or flexibility.

Test Yourself: Real Open Cosmos Questions

Three real prompts pulled from our database.

Type · Influence

Describe a situation where you had to influence a cross-functional team (e.g., engineering, sales, finance) to adopt a supply chain strategy or change they were initially resistant to. How did you approach it, and what was the result?

Type · Inventory Optimization

What strategies would you employ to optimize inventory levels for critical satellite components, balancing the need for availability against the high cost of holding specialized, long-lead-time items?

Type · Conflict Resolution

Tell me about a time you faced a significant conflict with a key supplier or internal stakeholder regarding a supply chain decision. How did you navigate the situation to reach a resolution?

Operations Case

3
Type · Optimization
Imagine we are experiencing significant delays in receiving critical satellite components from our primary overseas supplier due to geopolitical instability. How would you diagnose the root cause of this disruption and what immediate and long-term actions would you propose to mitigate the risk and ensure mission continuity?
4
Type · Network Design
Open Cosmos is expanding its constellation size and global reach. How would you approach designing or optimizing our satellite manufacturing and launch logistics network to balance cost, lead time, and reliability across different geographic regions?

Forecasting & Planning

5
Type · Demand Planning
How would you approach forecasting demand for satellite components and services, considering the long sales cycles, project-specific requirements, and the nascent nature of some markets?
6
Type · S&OP
Describe your experience implementing or improving Sales and Operations Planning (S&OP) processes. How would you tailor S&OP for a company like Open Cosmos, which balances recurring service revenue with bespoke satellite manufacturing projects?

Optimization

7
Type · LP Intuition
Explain the core concepts behind linear programming and how you might intuitively apply it to optimize satellite component sourcing across multiple suppliers with varying costs, capacities, and quality ratings.
8
Type · Route Optimization
Consider the logistics of transporting sensitive satellite components from manufacturing facilities to launch sites globally. How would you approach optimizing these routes to minimize transit time and cost, while also considering factors like security and environmental impact?

Behavioral / Leadership

9
Type · Ownership
Tell me about a time you took ownership of a supply chain problem that was outside your direct responsibility. What was the situation, what did you do, and what was the outcome?
10
Type · Influence
Describe a situation where you had to influence a cross-functional team (e.g., engineering, sales, finance) to adopt a supply chain strategy or change they were initially resistant to. How did you approach it, and what was the result?

Frequently asked questions

How long does the Open Cosmos 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 Open Cosmos?

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 Open Cosmos?

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.
