Many beginners think investment banking interviews are mainly about memorization. They’re not.
Interviewers care about whether you can:
- understand financial statements
- link business performance to valuation
- think logically through assumptions
- work comfortably inside Excel
- avoid breaking models
- explain your reasoning clearly
You do not need to build a 15-tab public company model from scratch as a beginner. But you do need solid fundamentals and enough repetition to become comfortable under pressure.
Step 1 — Learn Basic Concepts 3–5 days
Before touching DCF or M&A models, understand:
- income statement
- balance sheet
- cash flow statement
- how they connect
You do NOT need CPA-level accounting. But you must understand how the three statements interact.
If you can’t explain how depreciation flows through all three statements, modeling will feel like memorization.
Step 2 — Build a Simple 3-Statement Model 1–2 weeks
This is where real learning starts.
Focus on:
- revenue forecasting
- margin assumptions
- working capital
- debt schedules
- linking financial statements correctly
A clean, simple model is far more valuable than a complex, broken one.
Step 3 — Learn Valuation 1 week
Once the model flows correctly, move to valuation:
- Discounted Cash Flow (DCF)
- Comparable Company Analysis
- Enterprise Value vs Equity Value
You don’t need every edge case. You need to understand the logic behind valuation.
Understand where the numbers come from, what assumptions drive the valuation, and how changes in those assumptions affect the result.
Step 4 — Practice Like You’re Preparing for Interviews 1–2 weeks
This is the part most people skip.
Watching modeling videos feels productive. Actually practicing is harder — but it’s the only way you build interview-ready skill.
The fastest improvement comes from deliberate repetition, not passive learning:
- rebuild models multiple times without hints
- practice the same structure in multiple rounds until it feels automatic
- timebox each attempt as if it were an interview test
- explain out loud why you are building each step
- articulate trade-offs and assumptions as you go
Don’t just link statements — explain why a change in revenue assumption flows into cash flow differently than margin changes.
Interviewers don’t only care about the final model. They care about how you think through uncertainty, structure assumptions, and defend your logic under pressure.
Financial modeling is a practical skill. You build fluency through repeated, timed, and intentional learning — not by watching once and moving on.
Step 5 — Optional: Learn Basic M&A Modeling Concepts 2 weeks
If your goal is investment banking recruiting, especially M&A-focused roles, you can go one step further.
At a high level, understand:
- how mergers are structured (cash vs. stock deals)
- what accretion/dilution means
- how synergies affect valuation
- basic purchase price allocation intuition
You do NOT need to master full M&A models at the beginning stage.
Conceptual familiarity is enough at this stage. The goal is to understand the mechanics before worrying about advanced modeling.
Having this foundation will help you answer higher-difficulty interview questions and stand out in superdays.
Final Thoughts
One challenge with self-study is that it’s hard to know whether you’re actually building interview-ready speed and accuracy.
Consistency beats intensity. Even 60 minutes per day for several weeks is enough to become interview-ready for entry-level IB roles.
