How the rounds usually run

A typical consumer hardware loop for embedded roles. Companies vary by team and seniority.

Recruiter screen

• Background, role fit and logistics

Example: Walk me through your current project in two minutes.

Technical phone screen: C coding

• Live C coding: data structures, bit manipulation, memory
• Explaining your code and edge cases out loud

Example: Implement memmove and explain how you handle overlap.

Loop: embedded system design

• Architecture for a device feature end to end
• Power, memory and real-time trade-offs

Example: Design firmware for a wireless earbud's charging case.

Loop: RTOS, concurrency and debugging

• Scheduling, synchronization, priority inversion
• Hardware and software debugging with scopes and schematics

Example: Explain priority inversion and two ways to prevent it.

Hiring manager and behavioural

• Ownership, cross-functional work and judgement

Example: Tell me about a time you shipped under a hard deadline. What did you cut?
