I applied online. I interviewed at Bloomberg (London, England) in Nov 2025
Interview
Nice interviewer, was very understanding and went back and fourth throughout the question. You are expected to explain your approach and its time complexity. Medium question difficulty. Passed this round but failed the next technical round, There were 2 technical rounds, 1 system design round, 1 behavioral round.
Interview questions [1]
Question 1
Asked to design a FIFO "trading system" which was a Python class with 3 methods. Had a method to get the minimum value in the internal stack in O(1), required a monotonic stack. Asked to get k minimum values after, used a heap.
I applied online. I interviewed at Bloomberg (Dublin, Dublin) in Apr 2026
Interview
The first-round interview lasted about an hour and included questions about my academic background, projects, and motivation for joining Bloomberg. The technical portion focused on data structures, algorithms, and a coding/problem-solving question. The interviewer was professional and interested in my reasoning process, not just the final answer. I received positive feedback afterward and was invited to the next stage of the process.
Interview questions [1]
Question 1
I was asked a graph/search problem similar to finding the shortest path between two states. One of the coding questions was comparable to the "Number of Islands" or "Word Ladder" style of problem, where you need to traverse connected states efficiently using graph algorithms such as BFS or DFS. The interviewer was interested in my reasoning process, approach selection, and ability to communicate my solution.
1st round Technical interview. More stages after that but I didn't get that far. Apply through link provided as could not find a link to apply online. Asked about experiences on CV and why you would like to work at the firm.
