I applied through a recruiter. The process took 4 weeks. I interviewed at Bloomberg (New York, NY) in Jan 2017
Interview
I was contacted by Recruiter via email. The Recruiter then scheduled a telephonic interview that was about 45 minutes. I was given to implement an simple data structure problem and then follow up question. Next day I got email saying I have cleared the telephonic round and invited me for onsite interview.
The onsite interview had 2 technical rounds. Both were based on data structure and algorithm knowledge. My first round was really good and lasted for around 45 minutes, but second interviewer just questioned me as if he was not interested in asking.
I applied through an employee referral. The process took 2 months. I interviewed at Bloomberg (New York, NY) in Nov 2025
Interview
phone screen, one LC medium about backtracking and one medium using BFS/union find. Friendly interviewer and normal follow-ups.
Superday Round 1. one non-leetcode problem, like a OOP, easy to medium. One LC medium. Getting rectangle sum from a mutable grid, I cannot remember how to use a fewick tree so I just use a prefix sum, the interviewer is alomst satisfied.
Superday Round 2. One Leetcode Hard, find median in a data stream. Alot of followups on algorithm like why u choose this one not that one ... and a OOP. Interviewers are not friendly AT ALL with no hints.
