Experience
The interviewer was very polite. He asked about recent projects and reason why I wanted to work at Bloomberg. A mistake I made in this interview was that I started with the two pointer approach before explaining the Brute Force approach. It kinda gave away the fact that I had seen the question and solved it earlier. As a result, my coding was almost over in 20 minutes. Received a reject a week later.
