One-hour in-office interview.

There weren't any behavioral questions to speak of; the entire interview was solving small coding problems in C.

They had a bunch of skeleton files set up, and you could choose which problems you wanted to solve.

The interviewers were friendly but blunt.

They were willing to give hints if you got stuck.

They were understanding of the high-pressure environment of an interview and seemed lenient towards minor mistakes.

Seemed more interested in how you solve problems rather than whether you get them right immediately. A fairly casual interview.
