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.

These are the main technical questions that I had encountered in the two technical interviews: - Interrupt routine life time. - Pins of the SPI and its operation. - Causes of stack overflow. - Difference between memories in terms of speed/density/usage/cost/operation. -PWM operation and parameters. -Difference between startup code / boot loader. -In which memory the Interrupt vector table lies and in which position inside the memory. -Function that takes an array and eliminates any repetitive elements inside an array and returns it (find a proper way to return it). -Function that takes an array and prints another array with same size where the elements in the new array are the number of repetitive times of its indeces .in the input array. Example : Input = [1 2 4 5 6 2 4 0 2 2 3 3] output=[1 1 3 2 1 0 1 0 0 0 0 0] Explanation: 0 was repeated 1 time in the input array so we write 1 at the 0 index at the output array. 1 was repeated 1 time in the input array so we write 1 at the 1 index at the output array. 2 was repeated 3 times in the input array so we write 3 at the 2 index at the output array. 3 was repeated 2 times in the input array so we write 2 at the 3 index at the output array. 4 was repeated 1 time in the input array so we write 1 at the 4 index at the output array. 5 was repeated 0 time in the input array so we write 0 at the 5 index at the output array. ... and so on so forth
