I remember when we used to fight over whiteboards at work. I scavenged empty offices to get 2 extra large ones added to my office and thought it was the greatest thing ever. I had multiple on the walls of my house even. They were all full of binary trees that I couldn't invert.

Maybe I'm joking about some of that. But which parts? Anyway, the "whiteboard interview" where a software developer candidate has to write code or some algorithm on a whiteboard seems to have fallen out of favor recently. I had to do it a few times over the years and didn't really mind it too much. But I can see why it is a controversial interview technique.
