I&#x27;ve been asked a similar question which would have been perfect for this author.<p>I had recently published a (terrible, but also terribly fun to write) JavaScript physics engine, which the interviewer saw on GitHub. He began with, &quot;how does it work?&quot; and then continued with probing questions, getting deeper and deeper into the various problems I solved while developing the library, especially focusing on tradeoffs between various choices.<p>By opening the discussion on &quot;my turf,&quot; he put me at ease in the conversation, but by driving the interview with very technical questions, he also got the answers he needed about my technical ability.
