Cracking the Code: Mastering Investment Banking Brain Teasers for Interviews


Why investment banking interviews include puzzles

Investment banking interviews are notorious for including puzzles and brainteasers as a way to test a candidate's analytical thinking and problem-solving skills. These puzzles can range from logic and math problems to complex reasoning scenarios. The purpose of these puzzles is to assess how well a candidate can think on their feet, analyze information, and come up with creative solutions under pressure. Investment banks value candidates who can demonstrate strong critical thinking skills, as these are crucial for success in the fast-paced and high-pressure environment of investment banking.

One reason investment banking interviews include puzzles is to evaluate a candidate's ability to handle complex financial situations. Investment bankers often face intricate financial problems that require analytical thinking and attention to detail. By presenting candidates with puzzles during the interview process, recruiters can gauge their aptitude for handling such challenges. Additionally, these puzzles also provide a glimpse into a candidate's problem-solving approach and their ability to communicate their thought process effectively.

Investment banks also use puzzles as a way to assess a candidate's ability to work well in a team setting. Many puzzles require collaboration and teamwork to solve, which is a crucial skill in investment banking. By observing how candidates interact with each other and contribute to the solution of a puzzle, recruiters can evaluate their teamwork and communication skills. This is especially important as investment banking involves working closely with colleagues and clients to achieve common goals.

Common mistakes to avoid when solving investment banking interview puzzles

When solving investment banking interview puzzles, it's crucial to avoid common mistakes that can hinder your performance. Here are some mistakes to watch out for:


1. Rushing into a solution: It's easy to get caught up in the pressure of the interview and rush into finding a solution without fully understanding the puzzle. Take the time to read and analyze the question before attempting to solve it. A clear understanding of the puzzle will lead to a more accurate solution.
