two round interview: 1st: introduction of the company and yourself, the classic questions: what are your experiences, why you want to join the company;
if your 1st interview was successful: you'll be given an excel-sheet to analyze, it is fun if you the type to analyze such sheets.
The hiring manager was very friendly, but I was offered a different job which is even more interesting.
If you have the chance go to Vodafone, please do not hesitate to give it the shot:)
I can only recommend.
