The Information Management Group interview questions

First Round : 1 hour technical interview with the development management. Second Round : 1 hour coding exercise. My first round was good and I was called for second round. In second round I was asked to build a simple application using AngularJS and C# in 1 hour which was literally impossible. That too when the development manager had remote in to your laptop and passing comments every 5 minutes. Later was told to take the coding exercise home and finish it. I delivered it next morning but still got rejected. They didn't even gave any feedback or reason.
