Marsh Manager interview questions

I applied online, and after 2 days I received an email for video interview. In my opinion, it was quite awkward (answering questions to a computer screen). However, I answered all of the questions correctly. After the interview, it's been more than 2 months, I've not heard from them and I'm guessing I was rejected. It's really unprofessional of them, not to reply, even when it's a rejection.
