Bloomberg Interview Questions: What to Expect and How to Prepare

Bloomberg Interview Process

Bloomberg, a global leader in financial software, data, and media, is renowned for its integrated approach to combating the world’s significant financial challenges, utilizing cutting-edge technology and real-time data. For software engineers applying here, it's essential to demonstrate expertise in algorithms and data structures, as well as familiarity with Bloomberg Terminal functions, since engineers frequently contribute to its enhancements and innovations.

Bloomberg's interview process begins with an initial resume screening to assess candidates' educational background and relevant experience. Those who pass this stage typically encounter one or two online assessments (OA) focusing on coding and problem-solving skills, which can be quite challenging and are crucial for moving forward in the process.

Following the online assessments, candidates generally proceed to one or two phone interviews. These conversations aim to evaluate candidates' technical ability as well as cultural fit. Successful candidates are then invited to an onsite interview, which can consist of multiple rounds with different team members, further evaluating coding skills, system design, and communication abilities. The process is known for its rigor and thoroughness.

Initial Screen

Bloomberg's initial screening includes a detailed review of the applicant's resume, focusing on relevant software engineering experience and specific skills. Candidates may be required to complete Online Assessments (OAs) that test coding proficiency and problem-solving skills.

Following the resume review, selected candidates undergo a preliminary phone or video interview. This call typically involves behavioral questions and possibly some technical inquiries to gauge coding knowledge and logical thinking abilities.

Phone Screen

Bloomberg's interview process typically begins with one or two phone screens. These initial conversations focus on assessing technical skills and problem-solving abilities, often involving coding exercises or algorithm questions that candidates need to verbalize their thought process for.

The phone interviews also delve into a candidate’s experience and understanding of software development principles. This is an opportunity for applicants to demonstrate how their background and skills align with the responsibilities of the position they're applying to at Bloomberg.

Onsite Rounds

During Bloomberg's onsite interview rounds, candidates typically undergo three to four interviews. These sessions focus on coding skills, system design, and problem-solving abilities. Each interview lasts about an hour and is highly technical, emphasizing hands-on coding and design expertise.

Candidates can also expect a behavioral interview to evaluate their fit within Bloomberg's corporate culture. This is not just about technical ability but also interpersonal skills, communication, and adaptability. It’s a crucial part of the process and helps ensure a mutual fit.
