Domande di colloquio per SQL Programmer presso Two Sigma

I applied to this research analyst position. Then one guy called me and asked me if I know SQL. I said yes, but not very much. Then he asked about my programming skills. Well, I do not have much programming experience. The job that I am applying for is research analyst! Then he told me that it was a mistake of their recruiter. The job that he was interviewing for was a programmer position!
