How technicals are actually tested

The questions are a filter for whether you did the work. Holding that in mind makes preparation less anxious and more effective. Nobody is testing whether you are clever. They are testing whether you spent the weekends.

What each question is really measuring

Almost every technical question has a surface question and a real one, and the real one is in the follow-up.

• "Walk me through the three statements." Surface: can you name them. Real: do you know they are one system. The follow-up is a transaction, and that is the actual question.
• "Walk me through a DCF." Surface: do you know the steps. Real: do you know which cash flow pairs with which discount rate, and do you volunteer that most of the value is terminal.
• "Which valuation method gives the highest value?"Surface: a ranking. Real: whether you understand control premiums, and whether you notice the answer is "it depends" and say why rather than picking one.
• "What happens to the statements if depreciation goes up $10?" Surface: arithmetic. Real: whether you say cash goes up and can explain that the only real event was a tax deduction.

How to answer one

1. State the assumption you are using."Assuming a 25% tax rate" takes two seconds and prevents half the confusion.
2. Go in order. Income statement, cash flow, balance sheet. Not because it is impressive, but because it is the order the money moves, and skipping around is where people lose track.
3. Say the number.Not "net income decreases" but "net income decreases by $7.50". The number is the evidence.
4. Close the loop. End with the balance check, or the bridge, or whatever the completion condition is. Trailing off is the most common way a correct answer sounds incomplete.
5. Offer the mechanism. One sentence on why, after the what. That is the difference between someone who memorized and someone who understands, and it is audible.

What not to do

• Do not recite. A rehearsed paragraph delivered at speed sounds rehearsed, and the follow-up will land somewhere the paragraph does not cover.
• Do not pad. If the answer is one sentence, give one sentence. Filling time with adjacent knowledge reads as avoidance.
• Do not fake certainty. Interviewers ask follow-ups partly to find the edge of what you know. Reaching that edge and admitting it is fine. Reaching it and bluffing is not.
