Interview question
Walk me through how a $10 increase in depreciation affects the three statements.
Strong handling of the tax shield and the cash add-back. To reach a 10, close the loop on the balance sheet. Call out that net PP&E falls $10 while cash rises $2.50, so it still balances.

Frequently asked questions
What makes Prepor different from other resources?+
Prepor is built exclusively for investment banking recruiting by recent candidates who actually went through the process. Our platform allows you to practice real interview questions, get custom AI feedback that goes beyond right/wrong, and track your progress over time. We found that other existing resources are often outdated and built by people who may not fully understand the current interview environment.
Who is Prepor designed for?+
Prepor is designed for anyone looking to break into investment banking, whether they are applying to summer internships or full-time roles. We also view it as a resource for bankers in the industry who want to freshen up on relevant concepts.
What topics are covered?+
We cover the full spectrum of IB interview topics, including core technical questions like Accounting, Valuation, DCFs, LBOs, and M&A, as well as behavioral questions, product and market knowledge, and industry-specific questions.
Are the questions realistic?+
Yes. Every question on Prepor is modeled around questions that actually appear in investment banking interviews.
How does the AI feedback work?+
After you submit an answer, our AI immediately evaluates it against a rubric built around what strong IB answers look like. You get a score, specific feedback on what you did well or missed, and concrete suggestions on how to improve your response.
Are learning guides included?+
Yes. Your Prepor subscription includes full access to all learning guides. These cover foundational and advanced IB topics, including Accounting, Valuation, DCFs, M&A, LBOs, and more, so you understand the reasoning behind every answer. We spent a lot of time tailoring our learning guides so you can learn the required concepts efficiently.
Will more content be added over time?+
Yes. We're continuously expanding the question bank and adding new learning guides as the interview landscape changes. Subscribers get access to new content as it's released at no additional cost.
Can I cancel anytime?+
Yes, absolutely. You can cancel your Prepor subscription at any time, no questions asked. You'll retain access until the end of your current billing period.
What is the ROI of Prepor compared to failing interviews?+
The average investment banking salary is over $110k a year. The Prepor Season Pass costs $79, which is less than 0.1% of one year's salary. In that context, improving your interview performance can be worth far more than the cost of Prepor.
