The real reason first-year analysts fail isn't financial theory. It’s because their Excel and workflow habits are genuinely terrible.
I’ve been staffing and supervising incoming analyst classes for a couple of years now. Every single one of them comes in boasting about their finance degree, their understanding of advanced macroeconomic concepts, or how they can explain a DCF in their sleep.
Then day one hits, I give them a messy data dump from a client, and they spend six hours doing manual data entry because they don’t actually know how to clean data or build a dynamic model.
If you want to actually survive your first 90 days without getting flagged by your VP as a liability, drop the textbooks for a week and fix your technical workflow habits.
Stop using your mouse. Seriously. If I see an analyst reaching for their mouse every time they need to format a cell, trace a formula, or color-code an input, I already know they’re going to be lagging behind on deadlines. Force yourself to learn the keyboard shortcuts until it's muscle memory. It sounds trivial, but when it’s 2 AM and you have 40 slides to update, saving 5 seconds per action keeps you from sleeping at your desk.
Also, learn how to handle messy data. Real-world clients don't give you clean, pre-formatted financial statements like your university case studies. They give you broken PDFs, unformatted CSVs with missing dates, and conflicting ledgers. You need to know how to use power query, index match (or xlookup), and basic data parsing without breaking the audit trail.
If your model isn't dynamic—meaning if I change one growth rate assumption on the cover page and the entire 12-tab workbook doesn't automatically update perfectly—it’s a bad model.
Don't wait until your internship starts to figure this out. Build actual models using raw data from SEC filings right now.
