I am horrible at these kinds of interviews. I remember once being so nervous that I completely blanked. I'd been asked to reverse a linked list. A very simple task, one I'd even practiced a few times in various languages prior to my interview and should have been able to breeze through. But I froze. My hands were visibly shaking as the interviewer stared at my back... I shut my eyes tight, trying to think through the problem (I knew this was a simple task, and I was frustrated that I somehow couldn't recall the solution). At first I tried to write out a recursive solution to the problem, but my anxiety-riddled brain just couldn't cope with recursion that morning. So I erased the board and started over trying to find an iterative solution. That went even worse. "Um, I need to repeat this block of code, I think, maybe. There must be some way, some kind of construct that causes a block of code to be executed several times, almost as if one were looping through the code." AGH! Think! But I was coming up empty, I searched my memory, ready to seize on the first seemingly helpful thing I could find. And so my mind wandered back to a time when I was about 8 years old, learning to program for the first time on my Apple II. I had just discovered the magic 'GOTO' command, which was the perfect tool to cause uncomplimentary messages about my older sister's hygiene to scroll down the green mono display for all eternity (or until someone hit Ctrl-C). So... I completed my solution on the whiteboard using a GOTO. The interviewer put his face in his hands and began laughing. Eventually, he stopped and said "Um, ever heard of a for loop?" "Well.... yes."
