This time we're going to share a participant who just passed the Bloomberg 2026 New Grad SDE campus interview, the whole process from submission to two rounds of technical interviews only took more than a week, which is really efficient. The interview questions were all LeetCode Medium level, but the pace was very fast, the interviewers were very interactive, and the overall experience was surprisingly easy.
Bloomberg Interview Overview of the timeline
- 9.23 Delivery: Send your resume through the school's channels
- 9.23 HR InvitationI received an invitation to interview with HR on the same day.
- 9.30 School interview confirmation: Bloomberg Campus Interviews Take On-Site Mode
- 10.2 Face-to-face (technical + behavioral)
- 10.3 Second interview (technical + deep dive)
First round of interviews (10.2)
The first round interviewer was a very gentle Chinese lady and the atmosphere was very relaxed. She first exchanged pleasantries and then went into the standard Bloomberg behavioral question process.
Behavioral questions session
- self-introduction
- Describe one of your most representative project experiences
- Tell us about a project you found most challenging
- Describe a time when you were confronted with an ambiguous task requirement.
Bloomberg pays special attention to this "logic and communication in ambiguous situations" ability, and the lady asks very detailed questions, such as follow-up questions:
"And how did you communicate with the team to clarify the requirements?"
"Did the end result meet expectations?"
This part of the participant's answer was very natural and the pace was well controlled, with Miss nodding her head throughout.
Coding Title
Then into the programming part, the lady smiled and said, "Alright, let's have two coding to warm up~"
Q1: Validate Number of Triangles
Given an array, determine how many valid triangles (where the sum of any two sides is greater than the third side) can be formed.
Idea: Classic double pointer method, first sort, then fixed side traversal of the ends, a few minutes to write directly AC.
Q2: Flatten Linked List
strip next respond in singing child that requires flattening into a single-level linked table.
Idea: You can use either stack or recursive DFS. The students simulated with stack on the spot, and their ideas were clear, and they passed at once after writing it.
The young lady even joked when she saw the results, "Looks like I made the questions too easy, right?"
Smiling directly at the end of the interview, he said, "We have a second round at our school tomorrow, want to join us?"
(The trainee smiles and agrees, but in his heart he is thinking: another hour and a half in the car.)
Second round of interviews (10.3)
In the second round, there were two interviewers, an ABC guy with an Indian accent and an American engineer. The overall style was more technical and the questions were more in-depth.
Resume and Project Pursuit
Once it comes up it's still a resume oriented problem:
- "If you were to redo your previous project, how would you improve it?"
- "You mentioned smart pointers earlier, can you be more specific about the principle?"
This part is a little difficult, after all, the smart pointer that part of the project is a long time ago, the participants can only recall the concept on the spot, fortunately the tone of calm did not show fear.
Coding section
Q1: Find Level with Most Nodes in a Tree
Given a binary tree, find the layer with the most nodes and return the corresponding layer number.
Idea: Direct BFS hierarchical traversal counting the number of nodes, a sweep is done.
After only five minutes, the interviewers were nodding their heads and saying "Nice and clean!"
Q2: Trapping Rain Water
Classic catching rainwater problem, one of Bloomberg's love test questions.
The trainee first writes the regular solution, and then the American interviewer immediately asks, "And what if space O(1) is required?"
I was a bit confused on the spot, I forgot to write the monotonic stack, so I had to write a double pointer scheme in my head.
As a result, abc was actually super interested and immediately started discussing why double pointers can also satisfy space optimization.
At the end both interviewers smiled and said "Good reasoning, that's exactly what we like to hear."
Bloomberg Interview Summary
Generally speaking, Bloomberg's interview style favors "logical expression + follow-up reasoning", and the questions are not too tricky, but they test the depth of thinking.
- Coding Difficulty: LeetCode Medium level
- Behavioral component: Examining communication logic and reflective skills
- lit. inquire more closely: Like to ask "How would you improve this?", "Can you optimize further?"
- fast-paced: one round is basically limited to about 60 minutes
The feedback from the participants was that they had a good experience in the two rounds, the pace was smooth, the atmosphere was good, and it was the kind of interview that was "challenging but comfortable".
Programhelp Assisted Replay
The success of the Bloomberg interview could not have been achieved without the support of programhelp:
Pre-interview Mock TrainingI prepared targeted questions in advance based on the student's resume and job direction, especially the behavioral questions, and practiced the "vague task" type questions.
Voice Assist TipWe have a real-time hint "Start with BFS layers" or "Consider double-pointer optimization space" when you get stuck in the field coding.
No Trace Online Assists: The whole process simulates the natural conversation and programming process to ensure security and smooth answer performance.
We at programhelp have helped countless students from ordinary backgrounds to successfully get OA and interviews at major companies such as Bloomberg, Google, Amazon, Meta, and so on.
If you also want to efficiently handle Bloomberg school recruitment, VO or big factory OA, contact us at programhelp to customize the most suitable assisting solution for you, so that your next interview can also be a "full house".
