The Data Analyst Practice Platform I Wish I Had 12 Years Ago
DataSimHQ is an AI powered data analyst job simulation. You join fictional companies, receive briefs from simulated stakeholders, work with real databases, submit your work, and get graded feedback in seconds. Every task you complete builds a portfolio automatically.
In this walkthrough I take you through the whole thing:
The Work Desk, where you pick a company and a track. Meridian Retail, Nexus Financial Services, VitalCore Health Network, FlowRoute Logistics and Pitchside Soccer Co., each with its own branded database and its own business problems.
Three tool tracks. SQL, Power BI and Microsoft Excel, with tasks arranged from Junior Analyst up to Lead Analyst.
Real business requests. Not “build a bar chart”. Something closer to “build the Foundation page, four KPI cards, apply our brand styling”, written the way a manager would actually write it.
The AI Mentor. Ask it anything about the task and it will teach you how to think about it without handing you the answer.
Instant grading with specifics. It tells you exactly what passed, what could not be confirmed, and the steps to bring the work to full marks.
Design mockups on request. Copy a prompt, paste it into your AI tool of choice, and get back a polished reference layout so you know what good looks like before you build.
The Analyst Board. Rank against other analysts by XP earned, weekly and all time.
