Bloomberg Interview Process: Every Stage to the Final Round

How Bloomberg hires, from application and screening call to the in-house final round, based on its own careers pages, plus how to prepare.

Bloomberg's careers site says every job follows the same outline: an application, a screening call with the in-house Talent Acquisition team, an assessment for some entry-level roles, interviews, then an offer. In the Bloomberg interview process for software engineers, that means one or two phone or Zoom interviews, then in-house technical interviews (for experienced hires, about an hour each). Below are the stages as Bloomberg describes them, what its engineers say they assess, where outside guides disagree with Bloomberg's own pages, and how to prepare for the final round.

The stages Bloomberg publishes

Bloomberg's "How we hire" page lists six steps and says they apply to every job, with some differences by job function and experience level.

Stage — What Bloomberg says
Application — You apply to a specific role. Certain entry-level roles also require a Plum assessment, which Bloomberg says helps evaluate qualities important for those roles.
Bias Audit — Listed as a step, with no description.
Screening — A video or telephone interview with the in-house Talent Acquisition team.
Assessment — Certain entry-level roles require an assessment day or a task to evaluate job-critical skills.
Interviews — Described as a chance for Bloomberg to get to know you and for you to learn about its teams and culture.
Offer and onboarding — The final step.

The FAQ on the same page fills in some of the gaps. A recruiter reviews each application and contacts you to schedule an interview if your qualifications, skills and experience match the role, and Bloomberg warns that review can take time because of volume. You can follow your application under "My Profile" and then "Job Applications" on the careers site, and Bloomberg says you will be notified if the role is filled while your application is active.

Assessments vary by role. Talent Acquisition tells you if your role has one, and the examples Bloomberg gives are pre-recorded video interviews, virtual skills assessments, writing tests and technical or coding assessments. A pre-recorded video interview may test language proficiency, verbal presentation or technical ability. If you need an adjustment or accommodation to apply or interview, the page gives regional recruiting addresses to email.

Software engineering: from phone screen to final round

Bloomberg publishes separate interview pages for experienced engineers and for students and recent graduates. They describe two quite different routes.

Experienced hires. Bloomberg says the process is customized to the role, and typically starts with one or two phone interviews followed by in-house interviews:

First call: HR or an engineer, to understand your interests.
Technical phone interview: 45 to 60 minutes with an engineer. You need a quiet place and your computer. The interviewer assesses coding fluency, problem solving and computer science fundamentals such as data structures and algorithms, and leaves time for your questions about the team.
In-house round: from two hours to a full day, depending on the role and interviewer availability. Each round lasts about an hour with two engineers from the team you are interviewing for. Questions are open-ended, with several possible solutions, and test coding, problem solving, data structures, algorithms and design.

Students and recent graduates. Entry-level engineering and intern roles are not tied to a team: Bloomberg uses the interviews to learn your interests and find a team for you. As of the December 2025 copy of the student page, the process opens with a Zoom interview with an engineer, then two to three in-house technical rounds. Those rounds include a review of your resume and technical projects, coding in your preferred language, and both small problem-solving questions and larger design questions. Bloomberg also says it welcomes candidates who did not study computer science, as long as they can show problem-solving and technical ability.

For both routes, Bloomberg's FAQ names four things its technical interviews assess: data structure knowledge, algorithms knowledge, problem-solving skills and communication skills. It says it cares more about problem solving and coding fluency than about reaching the optimal solution or running the code. You can code on a laptop, a whiteboard or paper, in the language you know best. The student page also tells candidates not to worry about compiling the code, because thought process matters more than syntax.

Where outside guides disagree with Bloomberg

Third-party prep sites describe the Bloomberg software engineering loop with more detail than Bloomberg does, and they do not agree with each other:

Phone screen length. Interview Kickstart says the technical phone screen lasts about 30 minutes on a shared document. Bloomberg's experienced-hire page says 45 to 60 minutes.
Final round makeup. Aced (formerly Exponent) describes four to five rounds: two coding interviews, a 30 to 45 minute recruiter interview, and a final hiring manager round on system design, language tradeoffs and past decisions. Interview Kickstart describes three to five on-site rounds, including one or two system design rounds run by hiring managers and a behavioral round with a panel of three to four.
Online assessment. Educative puts an online assessment at the start. Bloomberg's pages say only that some roles have a coding assessment and that you will be told if yours does.

My read: these guides record what individual candidates saw at a given level and time. Bloomberg's own pages say no two interview processes are exactly alike, which explains much of the disagreement. Use Bloomberg's description as the baseline, and ask your recruiter what your loop contains; Bloomberg's FAQ invites you to ask for more information before an assessment. One point every source agrees on is design. Bloomberg's pages include design skills for experienced hires and design questions for students, so prepare for at least one design discussion at any level.

How to prepare for the final round

Bloomberg's own pages say what the final round looks at. These steps follow from what they say.

Make your resume the agenda. The student page says to expect questions about the projects on your resume and to be ready to explain the impact you made. For each project you list, prepare three things: the problem, the decision you made and why, and a result you can describe concretely. If you would change a design decision today, say so and explain why.

Run the first five minutes of every coding question the same way. Bloomberg's interview tips are short: ask for help, verify your assumptions, explain your thinking and listen carefully. In practice that means repeating the problem back in your own words, asking about input size and edge cases, stating a simple solution and its cost, and only then improving it. Because Bloomberg says it is not expecting the optimal solution, a clearly explained working approach that you then improve is a good outcome.

Practise in the format you will choose. You pick laptop, whiteboard or paper and your language. Decide before the day, and do your last week of practice in that exact setup. Writing code by hand on paper feels very different from typing it in an editor.

Talk to both interviewers. Experienced-hire rounds have two engineers from the team, which Bloomberg says gives it more than one view of how you performed. Explain your reasoning to both of them, not just the one who asked the question.

Know why Bloomberg, and have questions ready. The FAQ says interviewers want to understand what draws you to Bloomberg, how the role fits your long-term goals and how well you understand its business. It also describes a flatter structure than most large firms: roles are either individual contributors or people managers such as a Team Leader or a "Head of" a department. That makes good material for your questions, for example how work is assigned and reviewed on a team with that structure. Students should also be ready to name the areas they are interested in, because team matching happens through these interviews.

For question practice, our Bloomberg interview questions guide covers the behavioral side and our Bloomberg LeetCode questions cover coding. To prepare what you will ask your interviewers, try the questions-for-them tool.

Bloomberg's rule on AI and honesty

Bloomberg publishes an expectation on candidate conduct that every applicant should read. It encourages responsible use of all resources for research and preparation, and expects candidates to represent themselves accurately, from the resume through the skills shown in assessments and interviews. It says this applies to all resources, including AI.

In practice: use AI to prepare, and do the interview yourself. Practising aloud, with someone asking follow-up questions, is the part that is easy to skip when you prepare alone. Verve AI's mock interview has an AI recruiter ask you questions one at a time from a bank you choose, including Software Engineering and Finance banks, and gives you a scored feedback report afterwards.

Roles outside engineering

For roles outside engineering, Bloomberg's public pages give only the general outline above. Expect a screening call with Talent Acquisition. If you are applying for an entry-level role, you may also get a Plum assessment, a pre-recorded video interview or an assessment day. Bloomberg's interview advice for every role is the same: think about your motivation and how the role fits your career, learn how Bloomberg's business works, and bring questions, because it treats interviews as a two-way conversation.

After the final round

Send a short thank-you note to each interviewer within a day; our thank-you email generator gives you a starting draft to edit. Write down the questions you were asked while you still remember them. Then track your status under "Job Applications" on the careers site rather than chasing the recruiter early. Bloomberg says you will be notified if the role is filled while your application is active.
