The interview process for an Embedded Engineer at Zebra Technologies is designed to evaluate both your immediate technical capabilities and your long-term potential within the engineering organization. The process typically spans several weeks and progresses through distinct stages.

The journey begins with an initial screening, often initiated via a campus career fair, online application, or recruiter outreach. This is followed by a preliminary phone interview with the hiring manager. This conversation is structured to understand your background, your interest in Zebra Technologies, and your foundational knowledge of embedded systems. You should expect questions about your past projects, your programming language preferences, and your understanding of basic embedded concepts.

If you pass the initial screen, you will move to the technical evaluation phase. This may include a technical phone screen with a senior engineer or a take-home questionnaire focusing on C programming, bit manipulation, and basic algorithms. The final stage is a comprehensive panel interview, which can last anywhere from 2.5 to 5 hours. During this onsite or virtual loop, you will meet with four to six engineers and managers. This loop features a mix of deep technical deep-dives, system design challenges, and behavioral discussions.

The timeline above outlines the typical progression from your first contact to a final decision. Candidates should use this timeline to structure their preparation, focusing first on core C/C++ concepts and then shifting toward system design and behavioral scenarios as the panel loop approaches. While the exact duration of each stage can vary based on team and location, the rigorous evaluation of both technical and cultural fit remains consistent.
