There was an introduction interview were me and the technical manager were talking about our experience. When discussing several aspects he would point out that he has 20+ years in the field, and I would get to that point and will understand.. I got a home assignment that was sent to me based on the time and date I chose. It had several subpoins to implement including a websocket server, auth server, charts, some table. I did most of that, except the charts. After sending the code the guy writes back that "the charts were the most important part". That was never specified. And that is the last contact I receive from them after spending 3h of my weekend time for that assignment.
