It was a 3-stage interview process:

1st stage was about your basic knowledge in whichever profile you've been shortlisted for.

If you qualify that, they will refer you for the second stage where they will dive deep into the questions related to their project. They will check your ability to team up for this project or not.

In the last stage, the project manager will interview you.

Basic C programming questions:

• Macros
• Structures and unions
• Static variables
• Arrays and pointers
