Aegon Assistant interview questions

Online application was very straightforward - uploaded a cv and ticked a few boxes. After a few weeks got an email from hr inviting me to come for an interview and asking me to confirm a time. Once I had confirmed the date and time of my interview I had a reply confirming but no information on what the interview would actually be about. I was interviewed by two people. The interview included some general questions and some very specific ones (which I was told I should have known about in advance). The interview lasted around 20 minutes and I was told I would hear back by the end of the week. I never heard back from them.
