There is no OA for intern position. So I got 2 questions in my first phone interview. Start by asking why Bloomberg, then go over one of my projects. Then it is the technical interview.

Question 1
Given two unsorted arrays, return if you can form a pair that equals the target sum
I applied through a recruiter. The process took 3 weeks. I interviewed at Bloomberg (New York, NY) in Oct 2019
Interview
The whole recruiting process at Bloomberg was a very enjoyable experience. I was connected to the company via a recruiter I met at a conference who suggested I apply, which resulted in a phone screening. The screening involved some behavioral questions, but was mostly focused on a single medium-sized algorithms problem, which I did on a collaborative text editor online. Following that, I was invited to NYC for an interview day, which was a great experience in and of itself. I was taken on an office tour, I had behavioral interviews with an HR person and a senior engineering manager, and two 1+ hour coding interviews. Everyone at Bloomberg is super nice and welcoming, which made both the coding part and asking questions a lot easier.

I applied through college or university. I interviewed at Bloomberg
Interview
Pen and paper interview, requiring the code you write to be as close as possible to a compilable c++ syntax. Follow up was running time/memory. Also was asked about a previous project that I had worked on.
