Phone interview round - it was done with a software engineer and he guided me through the process of solving the problem. Two leetcode questions with some data structure follow-up questions. Just make sure you go through the most popular leetcode problems for Bloomberg tag. You will be fine. First onsite round - one hour interview with two software engineers. They asked two leetcode questions but more difficult than phone interview. (two city scheduling, candy crush 1d) They also asked questions about how to test the functions, etc. Although I didn't have enough time to implement the second question, they still let me pass to the next stage. Second onsite round - one hour interview with a senior manager at Bloomberg. He gave a paper of a description of the app he wanted me to implement. And he guided me through the whole process in terms of what class I need to implement and what kind of functionalities to include, etc.

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.
