Bloomberg Software Developer interview questions

I applied online back in Feb 2017. Received an email to provide availability for phone interview after a week. The phone interview was scheduled for 2 weeks later. It went well but didn't receive any email for a week. Contacted the recruiter and was told that I was invited for the in house interview. Due to weather conditions, my onsite interview got postponed by another week. The experience was good, like everyone else describes. Great office, lovely reception. First interview was with only one interviewer. It went pretty well. Didn't really expect me to code in any specific language. After first interview, was told to wait for 15-20 minutes. Second interview was with 2 interviewers. They were less friendlier but still polite and helpful. Could have done better but came up with solution for both problems. Was told to wait another 15-20 mins and was provided a sandwich for lunch. The weird part was having to sit in a conference room for the entire duration of the interview process. After the wait, was escorted out by another HR. That was when I realized that I would be rejected. Even though I was happy with my performance, I probably could have done better. The interview process was good overall.

Got a train ticket to New York city and 1 night hotel stay at Fitzgerald Grand Central Hotel. Arrived at the building at 11:30 for a noon interview. They checked my coat, gave me lunch, and took me up to a conference room. Then after a moment, 2 engineers came in to ask me technical questions.
