Example: What is the output of a signed and unsigned comparison in C, and why?

Technical 1: Embedded C and MCU basics

• Embedded C, pointers and memory
• Microcontroller peripherals and interrupts
• CAN fundamentals and your final-year or work project

Example: How does CAN arbitration work, and what happens on a bit error?

Technical 2: Automotive domain

• AUTOSAR layers, RTE and BSW
• UDS diagnostics and ISO-TP
• ISO 26262, MISRA and ASPICE awareness

Example: Where does a diagnostic request travel through the AUTOSAR stack, from CAN to the application?

Managerial or process round

• V-model and ASPICE work products
• Estimation, customer communication and reviews

Example: How do you handle a customer requirement that conflicts with a safety requirement?
