How the rounds usually run
A typical engineering services loop for embedded roles. Companies vary by team and seniority.
Online test
- Aptitude and reasoning
- C programming, electronics and OS basics
Example: What does sizeof return for a struct with a char, an int and a char, and why?
Technical 1: C and fundamentals
- Pointers, memory, data structures in C
- Your projects and the tools you used
Example: Reverse a singly linked list in place.
Technical 2: Domain for the project

- Scenario questions from real client work
Example: Explain how you'd add a new peripheral driver in the stack you know best.
Client interview (for project roles)
- The client's own technical screen for their programme
- Communication and ownership
Example: Explain your last module's design to someone who didn't build it.
HR
- Notice period, location and compensation
Example: Are you open to onsite assignments?
