After analyzing thousands of mock interviews, we've identified the most common technical mistakes that cost candidates offers. Here's what to avoid and how to fix it.
1. Not Knowing Your Resume Cold
Every number and experience on your resume is fair game. If you mention a valuation project, be ready to explain your methodology. If you list a GPA, know your exact number. Interviewers lose confidence when candidates stumble on their own experience.
2. Giving Textbook Answers Without Understanding
Memorizing that "depreciation is a non-cash expense" isn't enough. You need to understand why it matters and how it flows through the statements. Interviewers probe understanding with follow-up questions.
3. Forgetting the Tax Shield
When calculating the impact of depreciation or interest expense, many candidates forget the tax implications. Remember that deductible expenses save money equal to the expense times the tax rate.
4. Confusing Enterprise and Equity Value
This is a fundamental concept that trips up many candidates. Enterprise value includes all stakeholders, while equity value is just for shareholders. Know when to use each and how to bridge between them.
5. Not Walking Through the Three Statements
If you can't cleanly walk through how the three financial statements connect, you're not ready for interviews. This should be automatic.
6. Blanking on Basic Formulas
Practice until WACC, EBITDA, and DCF formulas are second nature. Nerves cause blanks, and nothing kills momentum like forgetting basic formulas.
7. Ignoring Reasonableness Checks
When doing mental math or market sizing, always sanity check your answer. Does a $500 billion market size for golf balls make sense? Probably not.
8. Not Asking Clarifying Questions
Many technical questions are intentionally vague. Asking "What industry is the company in?" or "What's the tax rate?" shows thoughtfulness and buys you thinking time.
9. Overcomplicating Answers
Start simple and add complexity only if asked. A clear, basic answer beats a confusing advanced one.
10. Not Practicing Out Loud
Knowing an answer in your head is different from articulating it clearly. Practice explaining concepts verbally, ideally to someone who can challenge you.
