Vodafone Project Manager interview questions

It was not very well organised. After submitting an online application, I got an email that I was shortlisted with a few general questions for me to fill in. I replied them with my answers and asked for an interview schedule but there was no reply. I called their HR manager a few days later to find out what was going on, and he apologised for not replying my email, saying that he was busy with other stuff and said that they were considering me, and would schedule my interview later. And then there was no reply again.
