Reading an exhibit in thirty seconds: from chart to “so what”

Most case interviews hand you a chart or table and wait. Describing it earns nothing. Finding the one movement that matters, and what it implies, earns the point.

Reading an exhibit in thirty seconds: from chart to “so what”

What is happening

An exhibit is a test of judgement disguised as a test of reading. Candidates under pressure narrate everything they see: “this line goes up, that one goes down”. The interviewer already knows what the chart shows. They want to know whether you can find the one or two facts that change the answer to the case, and whether you can say what to look at next.

The same skill is how senior people read reports at work. They skip to the largest change, check it against the question they care about, and ask one sharp follow-up. Practising it on exhibits trains the habit for every dashboard you will ever be sent.

Why it matters

Interviewers score insight, not description. A candidate who says “e-commerce produced all of the growth” in the first thirty seconds has shown more than one who reads every number aloud.

The framework

Four steps through any exhibit

  1. Orient in ten secondsRead the title, units, time period and any footnote. Say them aloud briefly.
  2. Find the biggest movementLargest change, largest share, or the outlier. Compute one ratio if it sharpens the point.
  3. Link it to the case question“This matters because the client asked about growth, and all of it came from one channel.”
  4. Propose the next questionWhat would you want to know to act on this? Margins by channel, customer overlap, cause.

What this means for you

StudentPractise on charts in business news: give yourself thirty seconds to state the so-what, then compare with the headline.
Fresh graduateIn interviews, ask for a moment to read, then speak in the four steps. Silence for ten seconds is fine; rambling for a minute is not.
Early professionalWhen you send a chart, write its so-what as the title. Your reader will thank you.
Experienced professionalAsk your team to title every exhibit with its conclusion. It exposes weak analysis before the meeting does.

What to do

  1. Rewrite the titles of three charts you have made recently as one-sentence conclusions.
  2. Do the drill below aloud, recording yourself. Count how many seconds pass before you say the so-what.
  3. Keep a list of useful ratios: share of total, growth rate, multiple of the smallest.
  4. End every exhibit with a question, not a summary.

Practice drill

A snack maker’s sales by channel3 min, timed

Your client, a snack manufacturer, asks how to keep growing. Sales in Rp bn by channel for three years: modern retail 120, 125, 128; traditional shops (warung) 200, 190, 176; e-commerce 20, 40, 72. Totals: 340, 355, 376. In under a minute, give the insight, the implication and your next question.

  1. Compare total growth with each channel’s change.
  2. Compute one share to make the point vivid.
Show a model answer

Insight: total sales grew Rp 36 bn over two years, and e-commerce alone grew Rp 52 bn, so e-commerce produced more than all of the growth while warung sales fell by Rp 24 bn. E-commerce went from about 6% to about 19% of sales; warung fell from about 59% to about 47%.

Implication: the growth question is really two questions: how to keep e-commerce growing profitably, and how to slow the decline of the largest channel.

Next question: what are margins by channel, and are e-commerce buyers the same households that used to buy at warung? If the channel is cannibalising rather than adding, the strategy changes.
