Given their background, perhaps a good focus on C for embedded systems, including:
- Static analysis tools (e.g. PC-Lint)
- MISRA-C.
- Exposure to multiple processors (e.g. PIC, STM32) and compilers
- How to debug.
- Real-time issues, including interrupts, debouncing signals, simple scheduling/RTOS.
- Software design.
And very significantly: version control software. I work in industry and use it religiously, yet I'm astounded that it was never mentioned in the course of my degree!
