Computer science, Linux commands that have to do with networking, text editing, file systems management , some basic electrical engineering such as floating points, fuse and mosfet functions. Software system levels and their descriptions.

The recruiter contacted me a long time after I applied, and the process itself took around two weeks. You’d be surprised by the way things are managed here—they lack proper time management and asked irrelevant, almost basic questions throughout the process. I’d only recommend applying if you're truly desperate; otherwise, it’s likely a waste of time. Check one of their job description and you will see the incompetency even there. This was the worst interview experience I’ve had.
