Excel for business analysts

A business analyst turns a vague question into a number someone will act on, and has to be able to defend how they got there.

What the job actually asks for

Translating a question into a measurable metric, comparing segments, and building reporting that someone else can rerun next month. The spreadsheet is as much a document of your reasoning as a calculation.

The recurring tasks

  • Translate a question into a measurable metric
  • Compare performance across segments
  • Build repeatable reporting templates
  • Document assumptions behind a model

Where people get caught

Building something that only works once. A one-off analysis with values pasted in cannot be rerun, so next month it is rebuilt from scratch — and the two versions disagree.

What interviews test

Conditional aggregation, defining a metric precisely, and being asked to walk through how a figure was derived.
