I applied online. I interviewed at Bloomberg (New York, NY) in May 2017
Interview
1. Technical phone interview: I was asked to code and solve one problem. It took around 30 minutes through HackerRank.
2. On-site interviews: I had two technical interviews and an interview with a senior manager. I was asked to write out solutions on paper. I wasn't expecting my third interview to be technical according to what I read here. But, I was asked to solve a third technical problem that was definitely more difficult than the problems during the first two interviews. I wasn't able to completely solve it but I kept going at it until the end.

I applied through university. The process took 3 weeks. I interviewed at Bloomberg (New York, NY) in June 2018
Interview
The process was very nice. They give you a travel stipend and a lunch in between your day-of interview. Process first began with them reaching out for a phone interview, then an onsite interview. Material was basic data structures since all applicants were high school students.
