Vodafone Internship interview questions

I got a phone call asking for my score in my Masters. Also, they asked me to fill two online test (one behavioural and one logical). After that they asked me to come to their Assessment day where first we had to present ourselves one by and one and tell why do we want to work at Vodafone. After that there was a Group Discussion regarding a business case. After that some of the candidates were given feedback and also had interviews with managers while a couple of candidates were given a negative feedback and were told to go back home. While I and some others were asked to stay and were given feedbacks at the end that in general feedback for all of us were positive. We had to wait 2-3 hours just for this and were told that managers who had to take interviews are not available right now, so they will let us know on the phone. After 5 days I went to the career day of my university and saw the same HR there and asked her for any updates. She told me that the internship position they were considering me for has already been filled.

I was asked few basic questions. Describe myself and the knowledge of networks. They described the parts of networking deppt here in Vodafone. Not much was asked as it was an internship. They cleared that no pay for interns whatever the kind of work you do.
