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.

There is an 8 bit counter that is incremented by hardware every tick call it counter8 And there is an interupt handler that is called every tick. I should write the code for the interrupt handler to implement a 16 bit counter.

There is an 8 bit counter that is incremented by hardware every tick call it counter8 And there is an interupt handler that is called every tick. I should write the code for the interrupt handler to implement a 16 bit counter.

Given are two functions. One function writes to the shared memory using the function write_to_mem() One function reads from shared memory using the function read_from_mem() We also have a 8 bit variable sem. First function can set/clear only the first bit of sem (msb), indicating it just wrote to the mem. Second function can set/clear only the last bit of sem (lsb) indicating it finished reading from mem. Both functions can read both bits. The two functions might run on different processor with different frequencies. Processor 1 runs a code that call the first function in en endless loop Processor 2 runs a code that call the second function in en endless loop. I need to write the code in each processor such that the functions are synchronized.
