CityBikes Ride Log

beginner·2 hrs

You just joined CityBikes, a city bike-share network. Your manager drops last month's ride log on your desk — 24 rides, six columns. Before Monday's ops review she needs the basics: how big is the data, who rides longer trips, and what per-minute pricing would look like.

FitPulse Session Cleanup

intermediate·3 hrs

You're a product analyst at FitPulse, a fitness-tracker app. The workouts table just landed as a CSV export — and it's messy: blank values where sessions didn't sync, the same activity spelled four different ways. Clean it first, then find which activities users actually stick with.

Wanderstay Booking Log Cleanup

intermediate·2 hrs

You just joined Wanderstay, a boutique hotel group with properties in Lisbon, Barcelona, Kyoto and Cape Town. The front-desk system's booking export is a mess — stray spaces in the headers, missing cities, a double export that duplicated rows, room types typed six different ways, and rates stored as text. Nadia in revenue ops won't touch it until it's clean.

Wanderstay Revenue Report

advanced·3 hrs

The Wanderstay booking log is finally clean — you cleaned it. Now Nadia wants the quarterly report: when guests check in, how long they stay, and a month-by-room-type revenue table she can drop straight into the leadership deck.

Zesto Late Orders

intermediate·3 hrs

One-star reviews are piling up at Zesto and every single one says 'late'. Priya, the City Operations Lead, wants to know: late *where*, late *when*, and late *why* — and she wants to see it, not read it. One month of orders, six charts, one answer.
