How to Become a Data Analyst

Data analysts answer business questions with SQL and visualisation tooling. It's the most common entry point into data careers for new graduates. Day to day, the work splits between building new capability and keeping existing systems trustworthy — the ratio shifts toward the latter as a company matures.

Interviews for these roles are usually four to six stages: recruiter screen, a technical screen on SQL or Excel, a deeper practical or design round, and a hiring-manager conversation about scope and ownership.

Months 1–4: get fluent in SQL and Excel. Build two projects that you could explain end to end in an interview, including what you'd change under load.

Months 5–8: add Tableau and Power BI. Start reading real job descriptions weekly and note the vocabulary gaps between them and your resume.

Months 9–12: apply in volume within the first 72 hours of a posting going live, tailor each resume to the posting's exact terms, and run every version through an ATS check before submitting.
