The phone interview was not smooth at all. After waiting twenty minutes, I ended up calling the company's HR Department and, magically, the HR Department knew that I was the one calling. I moved forward to the virtual interview with the hiring manager. The hiring manger got upset that I called the job position an experimental job position. In the end, I was rejected. I asked for feedback. They said that I was not "corporate" enough. What is that supposed to mean?
