An Ultimate guide for embedded/firmware engineer interview preparation

 

Field of embedded engineering is quite challenging and demanding. You need to be master of both the worlds software and hardware.

Here I have tried to compile entire list of my blogposts which can help you in preparation of embedded/firmware interview.

Note that most of the questions were asked in a real interview to me or some of my friends. So, you might have skipped lot of things in your life but don't skip here.

1) Prepare your self for C language questions :

Pro tip : Out of all interviews I have seen there are some generic questions asked on repetitively , like volatile , extern , static , or basic compilation flow etc , so prepare well for this basic questions.

2) Understand basics of compilers and cross compilers :

Well you need to have knowledge about your favorite IDE like keil , IAR , eclipse etc. But you should also have very good understanding of how compiler works , how code optimization works , what is linker , preprocessor etc.

3) Real time operating systems :

Accept it or not RTOS is integral part of embedded system and is a must have skill in your resume. I recommend no mater what prepare RTOS questions in your interview.

4) Prepare Hardware related stuff :

Well embedded engineering is half without hardware , and hardware knowledge is must for any engineer.

5) C++ and STL :

Now days there is lot of embedded development happening in C++ as well.
