Citi Financial Analyst interview questions

Five months ago, one of COOs at Citi Long Island City emailed me with the financial analyst position available. He called me firstly to ask some basic questions on my resume and two days later, he invited me to his office for the second round interview. It is not difficult because COO is not good at interviewing people. But I didn't get the offer due to their expense pressure.

it's a phone interview, It's mainly ask something about my resume. Candidates should be very familiar with their own resume. He insisted using English to interview me. And he actually asked the project I did and asked why I didn't continue doing which is not make sense since I already leave there. As I guess, he might be a HR instead of a analyst
