Intuition
An exhibit is a puzzle with the answer hidden inside it on purpose. The interviewer isn't testing whether you can read a bar chart — they're testing whether you can walk up to a wall of data, stay calm, and pull out the one fact that changes the case. Most candidates either freeze or read every number aloud like a court stenographer. The strong ones pause, orient, and then say "the interesting thing here is…".
Treat every chart as a question in disguise: why did they show me this now?
Framework
- Orient before interpreting (10–20 sec). Read the title, both axes, the units, and the legend. Say what the chart shows before saying what it means.
- Find the message, not every number. Look for the biggest gap, the steepest trend, the outlier, the crossover point.
- Tie it to the question. "This matters because it tells us the decline is concentrated in one segment."
- Do the implied math. Charts often hide a calculation — a growth rate, a share shift, a per-unit figure. Compute it.
Worked Example
You're handed a stacked bar of revenue by region over three years. Don't read all twelve bars. Orient: "Revenue in $M, by region, 2021–2023." Then scan: "Total revenue is roughly flat, but the West has fallen from $40M to $25M while the East rose from $30M to $42M." Insight: "So we don't have an overall demand problem — we have a regional problem masked by the East growing. I'd dig into what changed in the West." One sentence, and the whole case pivots.
Pitfalls
- Quoting numbers before checking the units (reading "$ thousands" as "$ millions").
- Narrating every data point instead of extracting the insight.
- Missing the hidden calculation the exhibit was built to make you do.
