Tableau or Selenium First? What Beginners Should Pick

Tableau — Learning Path:
Week 1: Connecting data, basic charts
Week 2: Calculations, filters, parameters
Week 3: Dashboards and stories
Week 4: End-to-end project

Daily focus:
• 1 hour theory + docs
• 2 hours hands-on in Tableau
• 30 min exploring community dashboards
• 30 min reviewing your own work

Week 1 Review:
□ Can I connect to a dataset?
□ Do I understand different chart types?
□ Can I build a basic chart?

Week 2 Review:
□ Can I write calculated fields?
□ Can I use filters and parameters?
□ Do I understand actions?

Week 3 Review:
□ Can I build a dashboard?
□ Do I know how to use containers?
□ Can I add a story?

Week 4 Review:
□ Have I built an end-to-end dashboard?
□ Is it published on Tableau Public?
□ Is it documented?

Selenium — Learning Path:
Week 1: Setup, locators, first test
Week 2: Waits, assertions, stable tests
Week 3: Page Objects, framework, reports
Week 4: CI + portfolio project

Daily focus:
• 1 hour theory + docs
• 2 hours writing and debugging tests
• 30 min reading Selenium patterns
• 30 min reviewing your code

Week 1 Review:
□ Can I install Selenium and a driver?
□ Can I write reliable locators?
□ Can I run my first test?

Week 2 Review:
□ Do I understand implicit vs explicit waits?
□ Can I use assertions?
□ Are my tests stable?

Week 3 Review:
□ Can I implement Page Object Model?
□ Can I use a test framework?
□ Do I generate reports?

Week 4 Review:
□ Can I run tests in CI?
□ Is my project documented?
□ Is it on GitHub?

Tableau vs Selenium — Side by Side:
Tableau:
  Purpose: Visualize data
  Output: Dashboards
  Role: Data Analyst
  Tool: GUI-based app

Selenium:
  Purpose: Test web apps
  Output: Test suites
  Role: QA Automation Engineer
  Tool: Code library

Decision Guide — Tableau vs Selenium:
Want to analyze and visualize data? → Tableau
Want to automate web app tests? → Selenium
Want to be a data analyst? → Tableau (+ SQL and Excel)
Want to be a QA engineer? → Selenium (+ testing fundamentals)
Want to be full-stack QA/Data? → Learn both
Not sure yet? → Tableau first (no coding required)

Action Plan — Which First?
Step 1 — Clarify your goal: analyze or test?
Step 2 — If data: learn SQL, then Tableau.
Step 3 — If testing: learn a language, then Selenium.
Step 4 — If both: Tableau first, then Selenium.
Step 5 — Build a project: dashboard or test suite.
Step 6 — Document and share on GitHub / Tableau Public.
Step 7 — Apply for roles that match your path.

Portfolio Review — What Hiring Managers Want:
☐ A real project (dashboard or test suite)
☐ Clean, well-documented work
☐ Clear problem statement and outcome
☐ README or methodology notes
☐ Live demo or published Tableau workbook
☐ Git history showing iterative work
☐ Full-stack data/QA project (bonus)
