The interview was mainly asking whether I was competent enough to do a software developer job with a non-software background, and whether I would be willing to learn financial knowledge, both of which I was asked three times with different way of asking. The interviewer was alright but was not very clear in talking, and there was a second person who stays quiet most of the time in the background, which sometimes made me slightly awkward. Will update this when I move on with the interview.
