I remember after deving a 50 player 3d networked multiplayer game in nodejs, that they became interested in interviewing me ( at the time node was only about 2 years old ). Unfortunately in the 4 hour pre-interview demo they wanted me to code, there was a deprecated call to a function I referenced later. Due to the time constraint I missed that one line of code. App worked flawlessly as I had tested it. Thing is I even knew I had a line of code somewhere that was deprecated but figured 4 hours was enough time to spend on a coding exercise, especially given, well , my 2 year demo project of a multiplayer game. As you can tell from the tldr; I was politely told they would not be interviewing me. All because of one trivial line of code, in a 4 hour demo done in my own time. To be honest, I knew the chap was giving me a chance to correct it by giving me a few days, but I thought it would be in bad faith to do it when I spotted the issue. Anyway, I didn't sweat it, I walked into a job at good startup, literally with gaffa tape on my sneakers and got it. They obviously make terrible decisions before even interviewing people in person.
