Embedded Software Engineer Interview Questions

Embedded software engineers develop and maintain embedded systems, which may require advanced software skills and problem solving. In an embedded software engineer interview, the interviewer may ask questions that test your coding skills and experience. Expect to also discuss how you work with others, as the role may function within a team.

Top Embedded Software Engineer Interview Questions & How To Answer

Question 1

Question #1: Define an embedded system.

How to answer
How to answer: Prove your competency by delivering a concise but thorough answer. Explain that an embedded system is a computer that lives within a bigger machine and operates in a unique way to perform a particular task. Consider offering some examples, like a car, a kitchen appliance, or an MP3 player.
Question 2

Question #2: What programming languages are you able to use?

How to answer
How to answer: Embedded software engineers are responsible for building complex functional systems, so it's beneficial to highlight your technical skills. The interviewer may want to hear you mention basic programming languages like C and C++. You might mention which languages you prefer or which you would like to gain more experience in, demonstrating passion and an ongoing willingness to learn.
Question 3

Question #3: Have you collaborated with engineers and designers?

How to answer
How to answer: You may work with others towards a common goal, so teamwork is vital. Consider sharing an anecdote about a time when you collaborated successfully to resolve an issue with a product. Focus on your ability to manage stress, clearly communicate complex issues, and listen to others.

Part 1: Implement a function that copies data from a source address to a destination address (just a one liner wrapper which uses memcpy). Part 2 : You now also have an API that triggers a DMA that can copy data efficiently, but it has a limitation that both the source address and the transfer length must be 8-byte aligned. Use this DMA API, and the API you wrote in part 1, to write an API that can copy any size of data from any source address to any destination.

They mostly ask about low-level Object-Oriented Programming. Electrical board related questions, Arduino. The preferred language is C++. They also ask about threads, deadlocks, and processes. Basic questions about OOP: Interfaces, Abstract Classes, Overwrite vs Override.
