Quad Capital interview questions

I spoke with one of the head traders. I had a phone "interview", although more a brief conversation. They mentioned that they like people with buy side experience, I said I have that, as I was a buy side analyst and a prop trader before that. They were extremely uninterested. My experience here is that they don't really look for analysts, although they mention on their website that they do. It was a negative experience and I would not recommend interviewing there.

After submitting application, I was contacted by phone for two interviews, with a potential for an in person final round interview. The first interview was with a trader, and the position was explained to me and I asked basic questions. The second interview was with a more senior trader, and involved several math questions. The interviewers we both polite.
