The hiring manager went through a 45-minute technical interview. They tried to understand your background, work experience, and finally asked technical questions in your area.

After a successful phone interview, they flew me in for an onsite interview, where you meet with different engineers. The schedule was tight, and they only had time for a 30-45 minute interview.

The interview was very technical, going over aspects of firmware development, debugging, implementing C code, and some problem-solving questions.

The problem-solving questions are easy if you are just out of school, but they would be difficult for old-timers because you have to remember geometry and trigonometry.

Given C code that involves double pointers, you have to dereference the double pointer. How will the double pointer look in main memory?
