Intercontinental Exchange Internship interview questions

I did the assessment first. It was followed by a phone screen. But the recruiter didn't call on the scheduled day, so I followed up-a lot! After about two weeks, I had the initial round. He then told me I will have two more rounds, and that he will send me a mail regarding availability. Again a period of no response. This time it was about a month even after numerous emails and calls. Then I get a mail from him saying I was not selected, and that someone else was supposed to be telling me this as he was on leave.
