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 Kraken Technology Group interview outcomes, avoid these common traps:
- Failing to extract all relevant information or creating an inconsistent output structure.
- Implementing heap operations (heapify-up, heapify-down) with off-by-one errors or incorrect parent/child index calculations.
- Not addressing data partitioning, replication, or fault tolerance adequately.
- Not correctly calculating the Euclidean distance between 3D points.

9 of 13 questions shown
Recruiter Screen
1- 1
Type · motivation
Kraken Technology Group is at the forefront of aerospace innovation. What specifically about our mission to revolutionize space access and our work in areas like satellite deployment or advanced propulsion systems excites you and aligns with your career aspirations?
Coding Screen
3- 2
Type · algorithmic
Given a stream of telemetry data from a satellite, where each data point is a tuple (timestamp, sensor_id, value), write a function to detect anomalies. An anomaly is defined as a sensor reading that deviates by more than 3 standard deviations from the rolling mean of the last 100 readings for that specific sensor. Assume you have access to a data structure that can efficiently store and retrieve the last 100 readings per sensor. - 3
Type · algorithmic
You are designing a system to optimize the trajectory of a small satellite for orbital maneuvers. You are given a list of waypoints (latitude, longitude, altitude, time) and need to find the shortest path between them, considering fuel constraints and gravitational pull. For this problem, simplify: Given a list of N points in 3D space, find the minimum number of 'hops' required to travel from point A to point B, where a hop can cover a maximum distance D. You can only move between points in the list. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Type · system-design
Design a distributed system for managing and processing telemetry data from a constellation of hundreds of small satellites. The system needs to ingest data in real-time, store it efficiently, and allow for complex querying and analysis by ground control and research teams. Consider data volume, velocity, variety, and the need for high availability. - 5
Type · system-design
Kraken is developing an onboard AI for autonomous satellite operations, such as collision avoidance or optimal power management. Design the system architecture for this AI. How would it receive sensor data, process it, make decisions, and execute commands, all within the constraints of limited onboard compute, power, and strict real-time requirements? - + 1 more questions in this round (sign up to unlock)
Onsite Coding
3- 6
Type · coding
Implement a function `parse_satellite_log(log_string)` that takes a raw log string from a satellite's onboard computer and parses it into a structured object. The log format is complex and can vary slightly. For example, a line might be `[2023-10-27T10:30:00Z] INFO: System temperature: 25.5C` or `[2023-10-27T10:31:15Z] WARN: Battery level low (15%)`. Handle potential malformed lines gracefully. The output should be a list of dictionaries, each representing a log entry with keys like `timestamp`, `level`, `message`, and potentially `value`. - 7
Type · coding
You are simulating a satellite's attitude control system. Write a function `calculate_attitude_correction(current_attitude, target_attitude, max_torque)` that determines the necessary torque adjustments to move from `current_attitude` to `target_attitude`. Assume attitude is represented by quaternions and `max_torque` is a vector. The function should return the required torque vector, ensuring it doesn't exceed `max_torque` in magnitude. If the target is unreachable within `max_torque`, return an indication of failure. - + 1 more questions in this round (sign up to unlock)
Behavioral / Leadership
3- 8
Type · behavioral
Describe a time you had to debug a complex, intermittent issue in a production system. What was your process for identifying the root cause, and what steps did you take to resolve it permanently? - 9
Type · behavioral
At Kraken, we often navigate the tension between pushing for an aggressive launch cadence and upholding the absolute rigor required for aerospace safety. Describe a specific time where you advocated for a delay or a change in technical direction because you identified a risk that others on your team were willing to accept. How did you quantify that risk to gain alignment, and what was the ultimate impact on the mission timeline versus the system integrity? - + 1 more questions in this round (sign up to unlock)

Sample answers
What a strong answer to these Kraken Technology Group interview questions shows.
Design a distributed system for managing and processing telemetry data from a constellation of hundreds of small satellites. The system needs to ingest data in real-time, store it efficiently, and allow for complex querying and analysis by ground control and research teams. Consider data volume, velocity, variety, and the need for high availability.
A strong answer shows: Scalability; Fault tolerance; Data ingestion strategies; Database selection (NoSQL vs SQL, time-series); Trade-off analysis (CAP theorem).
Describe a time you had to debug a complex, intermittent issue in a production system. What was your process for identifying the root cause, and what steps did you take to resolve it permanently?
A strong answer shows: Systematic debugging; Root cause analysis; Persistence; Learning from mistakes; Proactive problem prevention.
Frequently asked questions
How long does the Kraken Technology Group 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 Kraken Technology Group?
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 Kraken Technology Group?
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.
