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.

Assume we have a function get_book_info(isbn) that takes a string ISBN argument and retrieves a struct/object containing the Title, Author, and Language of a book (each represented as a string) that takes a nontrivial amount of time to run (perhaps because it’s making a call to a database). Write a wrapper function that increases performance by keeping results in memory for the quick lookup. To prevent memory from growing unbounded, we only want to store a maximum of N book records. At any given time, we should be storing the N books that we accessed most recently. Assume that N can be a large number when making decisions about choices of data structure(s) and algorithm(s).
