Collins Aerospace interview questions

Before I began, I applied for the electronic circuit role, and software development was my 3rd priority, I was asked questions about C, which was tough because I had knowledge of Python, Java, and C++, and nowhere in my CV did I mention C. 1. Intro 2. What are the stages of compiling in a C program. 3. What are the storage classes in C. 4. A simple programming question: how would you check if a number is a power of 2. 5. Do you know what bitwise operators are? (probably because I didn't use bitwise operators while solving q4). 6. Do you have any questions for me?
