• Bitwise Operations – Setting, clearing, and toggling bits, as well as masking and shifting for hardware register manipulation.
• Keywords and Qualifiers – Deep understanding of volatile, const, static, and how they dictate compiler behavior in embedded systems.
• Advanced concepts (less common) – Inline assembly, custom bootloaders, and hardware abstraction layer (HAL) design.

Example questions or scenarios:

• "Explain the volatile keyword and give a specific scenario where failing to use it would cause a system failure."
• "Write a macro or a short function in C to set the 5th bit of a 32-bit register without altering the other bits."
• "Walk me through how you would debug a segmentation fault on a system with no operating system and limited debugging tools."

Real-Time Operating Systems (RTOS) and Architecture

Mission systems require deterministic behavior. You will be evaluated on your ability to design software that meets strict timing deadlines and safely shares resources. A strong candidate will easily transition between discussing high-level architecture and low-level task management.

Be ready to go over:

• Task Scheduling – Preemptive vs. cooperative scheduling, rate monotonic scheduling, and identifying priority inversion.
• Concurrency and Synchronization – Mutexes, semaphores, spinlocks, and how to safely share data between tasks and Interrupt Service Routines (ISRs).
• Interrupt Handling – Best practices for writing efficient ISRs and deferring non-critical work.
• Advanced concepts (less common) – Multicore embedded synchronization, DO-178C software considerations, and specific RTOS internals (e.g., VxWorks, Green Hills Integrity).

Example questions or scenarios:

• "Describe priority inversion. How does a priority inheritance protocol solve this issue?"
• "What is the difference between a mutex and a binary semaphore, and when would you use each in an RTOS environment?"
• "Walk me through the lifecycle of an interrupt, from the hardware trigger to the execution of the ISR and returning to the main task."

Behavioral and Boeing Behaviors

Boeing places immense weight on behavioral questions to ensure candidates align with our safety, quality, and leadership standards.
