Bloomberg Software Engineer Interview Questions

If you’re a software engineer getting ready for the Bloomberg technical interview, you can typically expect questions around coding, systems design, and behavioral psychology. Even if you’re applying to roles like Machine Learning, Cloud Computing, Data Engineering, or DevOps, you’ll still have to demonstrate excellent problem-solving skills through your ability to solve tough coding problems. You would also need to exhibit the ability to build scalable systems and applications. 

Let’s look at some Bloomberg interview questions for software engineers on coding, systems design, and behavioral psychology. 

Bloomberg Interview Questions on Coding

 Coding forms the fundamental part of the Bloomberg software engineering interview. It also forms the basis of interviews for Machine Learning, Data Engineering, Application Development (Android, iOS), cloud engineering, and web developer positions. 

To solve Bloomberg interview questions on coding, you should be adept with the following topics -

Here are some sample Bloomberg interview questions on coding:

  1. If a rotationally sorted array is given, write a program code that finds a particular element.
  2. Write a code to check whether a binary tree is a valid binary search tree.
  3. Write a program that determines if the permutation of a string is a palindrome or not.
  4. Write a program that can check if a given binary tree is balanced or not
  5. You are given a string in a certain format of words. Create a program that will output the string characters in reverse.
  6. Determine whether any two integers added together equal a given value.
  7. The following input contains a two-dimensional array with all the elements of the array as unique positive integers. You should write a java program that will find all the arrays that do not have any element as zero.
  8. You are given two linked lists. List A has integer values, and List B has integer values. Write a program that adds the two linked lists and returns their sum.
  9. You're given the information to find the values at every level of a binary tree. Write a code that can do so.
  10. Write a program that swaps the opposite nodes of a binary tree.

  11. Write a code to find non-letter substrings that are palindromes. Original: The number of palindromes in S is the square of the number
  12. You’re given a list of stock prices and a code (number from 0 to 16). Write a program or command to tell at what levels, buying and selling, you can find the maximum profit.
  13. In an unsorted array with positive integers from 1 to n, there is an element where all numbers are between 1-n. Write a program to search for this element.
  14. Write a program to validate a given IP address.

Bloomberg Interview Questions on Systems Design

Systems design interview questions are an important part of the Bloomberg interview. Below are the important systems design topics to prepare for the interview:

  • Concurrency
  • API modeling
  • SQL and databases
  • Network systems
  • Sharding techniques
  • Caching and loading
  • Case studies

Below are some systems design questions to expect at the Bloomberg interview:

  1. What aspects would you consider while building a scalable software tool?
  2. How would you make sure your e-commerce system has low latency?
  3. What security aspects will you consider while setting up a database for financial entries?
  4. How would you build a chatbot service?
  5. Explain the design aspects to consider while building a scalable mobile application.

Bloomberg Behavioral Interview Questions

Behavioral and leadership rounds assess your ability to deal with a variety of workplace situations, how you manage work and life, challenging past projects, and professional challenges.

Below are some sample interview questions to practice for the Bloomberg behavioral interview:

  1. Tell us what you learned from the most challenging project you worked on.
  2. Why do you think Blomberg will help you advance in your career?
  3. How do you manage stressful situations at work?

Tips to Crack the Bloomberg Interview

To ace the Bloomberg interview, adopting a good strategy is key. There are various elements to a good strategy. That’s what we’ll discuss here.

Here are some noteworthy tips for adopting in your prep strategy:

  • Start early. Technical interviews have a lot of topics to cover, so make sure you start at least ten weeks before to give yourself the best chance. 
  • Identify patterns when you solve problems and classify problems with similar solution patterns. That way, you can use analogous patterns to solve new problems.
  • Solve at least 1 to 2 problems in core data structures and algorithms every day. 
  • Spend at least two weeks prepping systems design topics.
  • Spend at least a week practicing answers to behavioral questions.
  • Understand how remote interviewing tools work, as you might have to go through 2 or 3 remote coding interviews. 
  • Practice mock interviews with experts who can help you gain an edge. 
  • Create a good project portfolio to set yourself apart from the competition.
