What this role really is

Data Analysts answer business questions with data. Someone asks why a number moved; you find the honest answer and explain it to people who don't write SQL. Half the job is technical (querying, cleaning, checking your work) and half is communication — a correct analysis nobody understands changes nothing.

  • Investigate why a metric moved
  • Build dashboards people actually use
  • Write queries against production data
  • Present findings to non-technical teams
  • Recommend what to do next

Your 9-to-5, hour by hour

A realistic ordinary day — not the highlight reel.

  1. 9:00 AM

    Dashboard check

    You open the daily dashboards, spot that signups dipped 9% yesterday, and flag it in the team channel before anyone else asks.

  2. 10:00 AM

    Digging in

    You write queries slicing the dip by channel, device and region. It's isolated to mobile web in one country — which points at a release, not a market shift.

  3. 12:00 PM

    Stakeholder request

    Marketing wants last quarter's retention by cohort by Thursday. You scope it, push back on the parts that won't be reliable, and agree on what you'll actually deliver.

  4. 1:30 PM

    Building the analysis

    Clean, join, sanity-check. You catch a duplicate-row bug that would have overstated retention by six points.

  5. 3:30 PM

    Presenting findings

    Fifteen minutes with the growth lead: one chart, one sentence conclusion, one recommendation. They approve rolling back the mobile release.

  6. 5:00 PM

    Documentation

    You document the query, add the metric definition to the team wiki so the next person doesn't rebuild it, and close the ticket.

Great for you if

  • You get satisfaction from finding the real reason behind a number
  • You like explaining complex things simply
  • You're careful and hate being wrong in public

Probably not for you if

  • You want to build the product itself
  • You dislike repetitive data cleaning
