I applied online. The process took 4 weeks. I interviewed at Bloomberg (New York, NY) in Apr 2015
Interview
Three rounds: you are asked to leave after 2 if the performance is not good. I applied online and got an invitation for a phone interview pretty soon. There was a tour of the office before the interview where the HR walks us through the history of Bloomberg. There is no lunch interview: they give us a box of lunch in the morning and we can eat it between interviews.
Interview questions [2]
Question 1
Given a BST, find two numbers that sum to a given number.
Phone screen went very well, i passed to the onsites and they gave me the problem statement and i proposed a sub-optimal solution. They told to me come up with more optimal solution and didn't give me much time to think about it. They got impatient and gave me a hint. I figured it out and solved the problem, but apparently they thought I needed hints, which I didn't ask for.
15 minutes talking about resume, 45 minutes for 2 medium leetcode style coding questions (using code share), the interviewer was very friendly and communication is even more important than passing all test cases.
Overall, it was a positive and professional interview experience, though the interviewer was on the stricter side. Unfortunately, I was dealing with an illness and wasn't able to prepare as thoroughly as I wanted to, which left me feeling a bit off throughout the conversation. Despite not feeling my best and facing a tough interviewer, the process was well-structured.
