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.

you are given 2 integers. write a function that will tell us how many ones (1's) you should add to the second integer in order for that second integer to have the same amount of ones as the first integer. so for example if a=7 (111) and b=2 (010) the answer would be 2.

Describe & implement the function memcmp with the signature: bool memcmp(int[] a, int[] b). It should decide whether all the elements of a and b are equal, assume a and b are of the same length N for some N > 0. memcpm is required to run exactly the same code flow for all possible inputs (e.g. no return should be called until ran over all N array elements, even of non-equal elements have already been found).
