I applied online. I interviewed at Bloomberg in Sep 2017
Interview
Fast, the interviewer I had was unfortunately hard to understand and did not convey the question well. He also did not understand my runtime answers until iterating them for the second or third time.
Interview questions [1]
Question 1
Given a 10 million length string that doesn't fit in memory, find the unique characters. Implement a fork join algorithm using parallel programming.
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.
