How uniform are tech interview questions, in others&#x27; experience? I&#x27;ve had questions all over the place, often entirely unrelated to the position at hand. A while back, interviewing for a gig at Microsoft on a server related position, I was asked questions about triangle rasterization algorithms and z-buffers, by an entirely unrelated group. What is the point of these off the wall questions, and how or should one even prepare for these sorts of things?
