How the rounds usually run

A typical automotive supplier loop for embedded roles. Companies vary by team and seniority.

Written or online test

• Aptitude and logical reasoning
• C programming and core electronics
• Sometimes basic networking and OS

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?

HR

• Motivation, mobility and compensation

Example: Why automotive software?

Practice questions

Original questions written for Magna's focus areas, not leaked ones.

1. Design a HIL test for a power liftgate's anti-pinch feature.
2. How do you prove that every safety requirement has a passing test?
3. What makes a test flaky on a HIL bench, and how do you fix it?
4. How would you automate regression testing for nightly ECU builds?
5. Explain the difference between verification and validation with an example.
