Core tools

SQL Must have

The single most important skill for data analysts. Complex joins, subqueries, window functions, CTEs, and aggregations. You will write SQL every single day.

Used for: Data extraction, ad-hoc analysis, report building, KPI tracking
How to list on your resume

Show SQL depth: "Wrote complex SQL queries across 20+ table data warehouse with window functions and CTEs for weekly executive reporting."

Excel / Google Sheets Must have

VLOOKUP/XLOOKUP, pivot tables, conditional formatting, charts, and data validation. Many stakeholders live in spreadsheets.

Used for: Quick analysis, stakeholder collaboration, report formatting, data cleaning
Tableau / Power BI Must have

Building interactive dashboards that stakeholders use without asking you. Calculated fields, parameters, drill-downs, and publishing. Tableau is more common in tech; Power BI in enterprise.

Used for: Executive dashboards, KPI monitoring, self-service analytics
How to list on your resume

Mention dashboard impact: "Built Tableau dashboard tracking 15 KPIs used by 50+ stakeholders weekly."

Technical skills

Python Important

pandas for data cleaning, matplotlib for visualization, and basic statistical analysis. Not required for all analyst roles but increasingly expected.

Used for: Advanced data cleaning, automation, statistical analysis, large dataset handling
Statistics Basics Important

Averages, medians, distributions, correlation versus causation, and basic hypothesis testing. Enough statistical literacy to avoid common analytical mistakes.

Used for: Data interpretation, trend analysis, anomaly detection, experiment analysis
Data Modeling Concepts Nice to have

Understanding star schemas, dimension versus fact tables, and how data warehouses are structured. Helps you write better queries and collaborate with data engineers.

Used for: Query optimization, understanding data warehouse structure, data engineering collaboration

Business & communication skills

Business Metrics & KPIs Must have

Understanding revenue, churn, CAC, LTV, conversion rates, retention, and NPS. You need to know what these mean, how they are calculated, and what drives them.

Used for: Executive reporting, goal tracking, strategic planning
Data Presentation & Storytelling Important

Turning data into clear, actionable narratives. Choosing the right chart, writing clear annotations, and structuring presentations that lead to decisions.

Used for: Stakeholder presentations, executive reports, data-driven recommendations

How to list data analyst skills on your resume

Don’t dump a wall of keywords. Categorize your skills to mirror how job postings list their requirements:

Example: Data Analyst Resume

Analysis: SQL (advanced joins, window functions, CTEs), Excel (pivot tables, VLOOKUP), Google Sheets
Visualization: Tableau, Power BI, matplotlib, Google Data Studio
Languages: SQL, Python (pandas, matplotlib), R (basic)
Tools: Snowflake, BigQuery, JIRA, Confluence, Fivetran, dbt

Why this works: Leading with Analysis shows this is an analytical role. Listing specific SQL techniques signals depth beyond SELECT statements.

Three rules for your skills section:

  1. Only list what you’ve used in a real project. If you can’t answer a technical question about it, don’t list it.
  2. Match the job posting’s terminology. If they use a specific tool name, use that exact name on your resume.
  3. Order by relevance, not alphabetically. Put the most important skills first in each category.
