ING Energy Portfolio Analyst interview questions

I applied through an online posting on October 7th for an analyst position in New York. On October 19th a recruiter reached out to me to have a 20 minute pre-screening call. On November 1st I was invited to have a 30 minute interview with the head of the Portfolio Management group. I was expecting average behavioral questions as this was the first interview, but all the questions were highly technical regarding project finance and evaluating risk, how to analyze financial statements.
