What the deck covers
The deck mixes technical questions with the business-case questions that decide many analyst interviews. The 22 cards are grouped into 10 topics: Basics, Cleaning, Statistics, SQL, Excel, Visualisation, Metrics, Business, Tools, Data. Answers are short on purpose: one or two sentences you can say out loud, which you then back up with an example from your own projects.
A card from the deck
Q: Revenue fell 10% last month. How do you investigate?
A: Confirm the data is right, then break revenue down by time, region, product, channel and customer segment; separate volume from price; check events like outages, campaigns or seasonality.
This case question has no single right answer. Interviewers look for structure: check the data first, then break the number down step by step before guessing causes.
How to study with it
- Practise the case cards aloud with a timer; aim for a structured two-minute answer.
- Keep one dashboard from your portfolio ready to walk through.
- In the Data analyst deck, cards you mark "still learning" come back three cards later in the same round, and the results screen lists them so you can download a revision sheet.
