Bloomberg Software Engineer Interview Experience — First Round Was AI-Assisted Debugging of a Booking System

Bloomberg·Software Engineer·Nov 2026
Technical Screenmedium

Sharing my Bloomberg first round experience. It wasn't a traditional LeetCode algorithm problem, it was AI debugging.

They gave me a Python codebase of roughly 100+ lines that simulates a ticket booking system. The code already had some bugs in it, and the task was to debug it. You can use AI to help.

The bugs are the same as a few of the ones described for the Bloomberg booking question on an interview question database site.

From the discussion section there, it seems there are 5 bugs in total, but you don't necessarily need to find all of them. I saw someone who only found 4 and still passed, so it feels like it isn't purely about how many bugs you end up fixing, and communication with the interviewer is probably important too. I also feel this round evaluates how you use AI.
