Bloomberg Software Engineer Internship interview questions

Visited their booth in career fair, asked for on-campus interview a week later. First interview was with two software engineers. Simple tree question and some matrix processing question. They asked for second interview in afternoon the same day. Second interview was with one different software engineer. One algorithm question on whiteboard (can be found in leetcode). Received rejection email after a week later. (I heard Bloomberg prefers C++, but they doesn't really care and let's you use any language.)

The process was great. They are great with communication and fast with replies. I passed the phone screen and received first round interview. I didn't pass that but I believe they fly you out for your third round interview.
