Garmin's Interview Process (2026)
Blog / Garmin's Interview Process (2026)

Garmin's software engineer interview process is generally a 3 to 4 stage pipeline that most candidates complete within a couple of weeks. The format and emphasis can vary by team, but expect a consistent focus on core CS fundamentals and practical implementation over algorithmic tricks.The final panel covers a range of topics, so it helps to structure your prep around the main areas Garmin consistently tests:1. Data Structures & Algorithms (DSA)Garmin's coding questions lean toward practical, bread-and-butter problems rather than competitive programming puzzles. Candidates in 2025 and 2026 report seeing questions like Reverse String, String to Integer (atoi), and Merge Sorted Array, so start there.Array and matrix problems also appear regularly. Expect questions like a two-sum variant, finding the difference between max and min values in an array, or searching a 2D sorted matrix. Brush up on matrix and sorting algorithms before your interview.For a structured starting point, work through our top 100 DSA questions to make sure you have the fundamentals covered. Garmin's bar is solid but not esoteric, so quality of explanation matters as much as arriving at the right answer.2. CS FundamentalsGarmin interviewers are known for asking direct conceptual questions, not just coding problems. Common topics include stack vs. heap memory, how a HashMap handles collisions internally, and the difference between pass-by-value and pass-by-reference.Concurrency is another area that comes up, particularly mutexes and semaphores in multi-threaded or embedded contexts. Even for roles that aren't purely embedded, having a working understanding of how software interacts with hardware gives you a real edge. Reviewing operating systems concepts is a good way to solidify this area.Expect interviewers to go deep on whatever you put on your resume. They are known for asking about specific projects and bugs you have fixed, so be ready to walk through your own work in detail.3. System DesignGarmin's system design questions are grounded in the constraints of real devices. A common prompt is designing a GPS coordinate logging system that minimizes battery and memory usage, which requires thinking about hardware limitations, not just abstract scalability.Other reported prompts include architecting a data pipeline for wearable sensors. These questions reward candidates who can articulate trade-offs clearly, such as choosing between polling and interrupt-driven approaches, or trading off storage frequency for battery life. Check out High-Level Design to build your foundation, and practice drawing out your architecture with our System Design AI Whiteboard.Garmin also includes a team-placement round where leads from different product segments (Aviation, Fitness, Marine, etc.) assess fit. This is a good opportunity to show genuine interest in a specific domain and demonstrate that you understand the technical challenges of that product area.4. BehavioralThe behavioral round is typically a 1-on-1 with a hiring manager and focuses on how you work with others, handle ambiguity, and communicate under pressure. Garmin is noted for valuing a low-drama, steady communication style over candidates who oversell.Prepare concrete examples from past projects and structure your answers clearly. Using the STAR principle is a reliable way to keep your answers focused and easy to follow. Our Behavioral Interview Course covers the most common question types in depth if you want to go further.ConclusionGarmin rewards engineers who understand the reasoning behind their technical decisions, not just the solutions themselves. Practice talking through your thought process out loud, revisit your C/C++ fundamentals, and make sure you can speak confidently about your own past projects. Follow the Garmin Interview Roadmap for a step-by-step plan to prepare for every stage of the process.
- Recruiter Screen: A short introductory call, usually around 30 minutes, to discuss your background, interest in Garmin, and general fit for the role.
- Online Coding Challenge: Typically hosted on HackerRank, this challenge tests core coding ability. Some specialized teams use custom puzzles in place of or alongside a standard challenge.
- Technical Screen: A virtual interview, often via Microsoft Teams, with one or two engineers. Expect questions on language proficiency (C++, Java, or C) and foundational computer science concepts.
- Onsite / Final Panel: A multi-round session, either virtual or in-person, usually running 3 to 4 hours. It typically covers technical depth, system design, team placement, and a behavioral round with a manager.
- Data Structures & Algorithms (DSA): Back-to-basics coding problems focused on arrays, strings, sorting, and core data structures.
- CS Fundamentals: Memory management, concurrency, and OOP concepts tested through direct questions and live discussion.
- System Design: Designing real-time, hardware-adjacent systems with an emphasis on constraints like battery and memory.
- Behavioral: A 1-on-1 with a manager focused on teamwork, adaptability, and clear communication.
