Standard Chartered Bank Analyst interview questions

Got a call from HR for asking if I'm interested it or not, I said yes then went through the interview process. Since I'm in the states and the interviewers are in Singapore, it's just phone interview. They need someone to work on their system, and their business focusing on fixed income on emerging market and FX options. They mainly asked some finance questions, like basic knowledge on options, how to derive black-scholes formula, and some C++ and SQL questions. It's basically not a tough one.

The whole process took around two months but then no offer at the end.
