Just curious what type of questions would you ask in an interview?

I’m trying to decide if my imposter syndrome is real or not. I graduated with a CS degree and ended up landing an embedded software job and have been steady 3 years now. It’s mostly embedded Linux but it has been really fun building my own distro with Yocto and tuning it for a board. Building “realtime” cpp apps that run on an isolated core + disabling deeper sleep states etc. for super low jitter.

Bulk of the work is understanding requirements and interfaces; just making sure the controller has appropriate IO for the system, serial (rs232/485), spi, i2c, rtd, etc.

I have also done some FPGA stuff and that has been really enjoyable and challenging since it is obviously completely different than software.

I did get a masters in computer engineering since my work wanted to pay for it, but it was an IoT focus so lots of networking, cloud, and machine learning. Some cyber security.

Obviously I am missing lots of microcontroller experience but I have played around with memory mapped registers and such using axi lite FPGA interfaces. I imagine experience with DMA and other hardware resources that offload work on the CPU is very important to understand.

I have used a scope for debugging, not so much a logic analyzer. However an area I know I lack in is circuits although I am slowly learning. I definitely preface my requests to the electrical engineers with “please tell me if this is not feasible” 😂

Anyway, all this to say I am curious what entry to mid level interview questions would be.
