I was asked once during an interview to describe a specific problem that I enjoyed solving. And I was told to go in as much depth as I could during the timeslot.<p>I thought that was a great question. It got me talking about something I cared about, knew very well, and showed my <i>normal</i> thought process and development process outside of an interview. It also gave the interviewer plenty of things to ask about, to &quot;quiz&quot; me on if they wanted, or to just make sure I could actually code.<p>If I&#x27;m ever in a position to interview someone one-on-one, that&#x27;s most likely going to be my main question.
