IHS Markit interview questions

Applied through linkedIn. Was asked for a phone screening by a senior manager. It was easy and lasted for 10 minutes. He asked some basic questions like OO principles and database concepts. Got an email next day saying that they want to set up a call with three of the senior software engineers. Even the second round was easy, they asked some basic questions related to agile methodologies. And they were satisfied and set up a Skype call for the third round. And the day before the call, I got a mail saying I was not selected. I do not know what really happened. They dint even give me a reason and sent me an automated e-mail.
