The interview was through college career fair. There was an information session where students got to ask the hiring manager and a software engineer questions about the company, what they do etc.

The interview included basic behavior questions, such as why do you want to work for us, where do you see yourself in 5 years, do you think you have the right discipline to work at our company (considering top secret clearance), and the nature of what they do.

How do you test a function that adds, subtracts, multiplies and divides? How do you manage 3 members who have great but different ideas on a project?
