Worldline Senior Software Developer interview questions

Worldline Pune: Applied through recruitment Institute. Initial screening process were smooth. Performed well in first round of technical discussion. Then in next managerial call, I end up hearing this. The manager said to me "Interviewer had informed him that I had already joined another company". Ironically both techniqcal and manager round was on same day for Wolrline. And i was giving interview with them. This created negative impression on me in respect to Culture and Values of Company, since am an outsider to company who was aspiring to join. But such ineffective skills of communication had created bad benchmark, like what will happen if had joined the company!
